The Grind, presented by Bank of Clarendon: Sumter High, P-15 ace Davis ready to take the next step at Florence-Darlington

Consistency is among the most important attributes that an athlete can have in pretty much any sport. Highlight performances are great, but the elite players go out and perform night in and night out.

That's exactly what Marion Davis has done for his entire career.

The 2026 graduate from Sumter High doesn't have the most dominant fastball in the area, though he's made great strides in velocity since making the jump to varsity baseball as a freshman with the Gamecocks. But pitching is about so much more than putting up big numbers on the radar gun. From Day 1, Marion has been able to put pitches exactly where he wants, making opposing batters look pretty silly in the process. Throughout his entire career, Marion has done the one thing that every coach asks of their starting pitcher: Give us a chance to win tonight.

"He's kinda one of those guys that every coach wants to have, the type of pitcher that only comes around every once in a while," said Will McMillan, who coached Davis at Sumter High for the last four years. "Any time he was on the mound, not just from the coaches' standpoint, but I think the team's standpoint, you felt like you could beat anybody and you had a chance to win. He was going to keep you in the ballgame."

GROWING UP PREPARED

FOR THE JUMP

Marion is the youngest of four kids. His two older brothers, Knowlton and William, all got a head start on sports, but Marion wasn't far behind. He wanted to keep up with his dad and older brothers and wasn't afraid of playing with the older crowd.

"Pretty much anything from an athletic standpoint or a competitive standpoint is natural for him; that's something he's always enjoyed or wanted to do," said his father, Knowl. "If I was doing anything with his older brothers, he was right there with us. If we were out in the yard or out at Bobby Richardson Park, he was right there with us. It was just sort of natural for him to be included, and he loved every minute of it."

William is 13 months older than Marion, so the future SHS ace typically played at least a year up so he could team up with his brother. It didn't hamper his ability to shine.

"In some instances, it was sort of sink or swim, and he usually did a pretty good job of swimming," Knowl quipped.

Pretty much as soon as he entered kid pitch, Marion started taking the mound. When he wasn't pitching, Marion manned shortstop, but the mound quickly became a second home.

"I definitely love being in control of the game, being able to take it at my tempo and on my time," Marion said of what drew him to pitching.

FRESHMAN LEAP

Playing against an older crowd for most of his life helped prepare Marion to make the jump to varsity as a

freshman. Will came over to Sumter High as Marion was entering his freshman year but watched his future ace pitch at the JV level during his time at East Clarendon. At that point, he was pretty confident that Marion had the necessary skills to play on varsity as a freshman.

"I remember seeing him as an eighth-grader before I even got to Sumter thinking, 'Dang, this guy is only in the eighth grade? He's going to be special,'" Will said.

Confidence was key for Marion as he made the transition to varsity baseball. He wasn't overly worried about the ages of his opponents; he was just focused on getting outs.

"I tried to not let it affect me at all," he said. "I kinda didn't care who I was throwing against, I was just kind of confident in myself and confident that I could get them out. But it definitely was a big adjustment at first. When I was a freshman, I gave up a ton of hits, but I kind of figured it out."

Marion did give up a few hits as a freshman - a team-high 52 to be exact - but he still managed to pitch to a 3.50 ERA across 44 innings of work. He made six starts and had two appearances out of the bullpen, earning a save and three victories.

The future ace had two key reasons for his success. The first was his excellent command. He only walked three batters his entire freshman year, and two of them came in the same game. He had a knack for hitting his spots; he just needed to learn how to make sure those spots weren't prime locations for opposing batters to make solid contact. While he didn't throw particularly hard as a freshman, his excellent changeup still kept hitters off-balance at the plate.

"As a freshman, one of the things that stood out was his ability to locate," Will said. "His ability to locate and having that changeup; even though teams knew he was going to throw the changeup, it was so good that it was hard to decipher that from his fastball. There were so many times a guy thought it was a fastball and came unglued and were way out in front of it, getting them to pop out or hit a ground ball."

The other characteristic that led to early success was his composure. Marion's stoic nature on the mound - which is completely different than his joking nature away from the bump - helped him stay locked in from Day 1.

"He just came in there, and nothing fazed him. He was always calm and kept his composure, and that was one of the biggest things with him," Will said. "I know he put a lot of pressure on himself over the years and wasn't always happy with his performances on the mound, but on the mound, very rarely did you see his facial expression change or get upset.

"Everything was very business-like for him. That was one of the biggest things that led to his success, the way he was able to keep his composure. The moment never really got too big for him, and you always knew what you were going to get. He was always going to come in and throw strikes."

While Marion rarely let his emotions show on the mound, he admits that there are still nerves before starts. Once he fires that first pitch - usually for a strike - he quickly settles in.

"A lot of times I'm just really nervous before I pitch. Once I throw the first pitch, I'm all good from there, but a lot of times, I'm just trying not to get myself too excited before the game," Marion said. "Once I throw the first pitch, a lot of the times, I feel a lot better."

As a parent watching from the stands, Knowl has always appreciated his son's ability to manage his emotions on the mound. Whether a start is going well or not, you always get the same version of Marion on the bump.

"He can be a cut-up, he can be goofy at times, he loves to joke around, but when it's his time to go to work, what I admire about him is that he's extremely competitive, he wants to do his absolute best, and he's never satisfied with however the game went," Knowl said. "He's looking to improve all the time, and that's really been his MO since joining varsity, at least. He has one aim on the mound, and it's to do the best he can to put the team in a position to win. He's very driven in that regard."

CONTINUING TO IMPROVE

With each year that passed, Marion kept improving. As a sophomore, Marion was unstoppable. He pitched to a 1.00 ERA, which led the team, and had a WHIP (Walks and Hits Per Inning) of .768. He allowed just 33 hits and 10 walks across 56 innings on the mound, striking out 51 batters.

One of Marion's biggest strengths, which has lasted throughout his career, was his ability to pitch deep into games. He threw a complete game in nearly every start as a sophomore because of his ability to force weak contact for easy outs. His elite changeup was his greatest weapon.

"It's really just a four-seam changeup, but it's a circle change, as well," Marion said of his signature pitch. "I just try and come over the top of it to kill the spin and make it drop off. It causes a lot of pop ups, which is what I've had throughout my entire career. It's definitely a big part of me as a pitcher."

Marion put together another excellent season as a junior, leading the team with a 1.39 ERA and 58 strikeouts in 55 1/3 innings.

But if you ask Marion, he didn't fully become a pitcher until the following offseason. That's when he started working with Brandon Williams, who serves as the pitching coach at Ben Lippen. He really helped Marion build up his velocity, hitting the upper 80s with his fastball.

"It definitely wasn't until recently where I felt like I improved a lot. I was good when I was in like ninth and 10th and 11th grade, but I really just threw strikes. That's really all I did, I wasn't really that good," Marion said. "Over the winter last year is when I really started to feel a lot of those improvements come. It definitely showed in the high school season.

"I started going to a pitching coach in Blythewood, and he really helped me. I never really had a pitching coach help me specifically with throwing harder and throwing better pitches, so I feel like that helped me a lot. I was definitely working out a lot during that time, as well."

Marion continued to be a rock for Sumter High this spring, pitching to a 2.85 ERA, though two tough starts against Blythewood and River Bluff are the main culprits for the elevated number. He walked a few more batters as he adjusted to his improved velocity but also set a career high in strikeouts with 75 across 61 1/3 innings of work. He was 7-1 and earned All-State honors. While he may have had a lower ERA earlier in his career, Marion felt himself develop into a true pitcher in his final season.

"When I was a freshman, I wasn't really that focused on the pitches that I was throwing and what I was doing with them and what I was trying to do with pitches," he said. "Now, I've been working more on taking the game one pitch at a time and just throwing that pitch in that moment and, no matter what the outcome is, focusing on the pitch you're about to throw. That's definitely helped me a lot throughout my career."

GROWING ALONGSIDE THE PROGRAM

As Marion grew up in the Sumter High program, the Gamecocks grew with him. SHS was built around a stellar senior class this spring, and the program took strides every year of his career.

Before Marion made the leap to varsity, the Gamecocks were in a bit of a playoff drought. They finally snapped that streak during Marion's freshman season in 2023, going 12-14-1 with a playoff victory in tow. While Marion was aware of the importance of their playoff berth, it wasn't necessarily on the front of his mind entering the season.

"It wasn't as big of a focus for me because I was more focused on not getting cut and stuff like that," Marion quipped. "I definitely do remember that the varsity team wasn't as good my freshman year and maybe the year before that, but I realized that there were a lot of people there my age like Gavin (Rivers) and Joseph (Chapman) and Morgan (Love) and all of them. We all kind of grew up together and started affecting the program a little bit."

And they kept getting better every year. As a sophomore, Marion and the Gamecocks went 15-9 and earned another trip to the postseason. As a junior, SCHSL 5A split into two classifications and overhauled the playoff system. Sumter High was 14-11 in the regular season but needed to win a best-of-three series with Ashley Ridge to earn a spot in the district tournament. They took two of three to advance to the district but dropped their two road games to end their season.

This spring, everything fell into place. Despite an early rash of injuries that limited their pitching staff and a cold stretch in the middle of the season, Sumter High was once again in the postseason. They faced West Ashley in another best-of-three series to earn a spot in the district. Marion led SHS to a 7-0 win in the opening game before they fell 7-3 in Game 2. Sumter High then had a ridiculous third game, where they rallied for six runs to take a 7-5 lead in the fourth only to immediately fall behind 9-7. With their backs against the wall, Sumter High scored five runs in the sixth to take home a 12-9 win, setting up a wild postseason run.

"It was definitely really fun. It's definitely a good thing because it's really memorable, but for a little bit I was like, 'Oh crap, we might lose,'" Marion admitted. "But it was definitely a crazy win. We have a couple of guys who always like to make it close. It was fun, but it was a great comeback."

The game was a microcosm of the Gamecocks' growth over the years. They learned from their mistakes and had a never-say-die attitude that helped them keep their season afloat. Winning in the postseason shifted from being a pleasant surprise to becoming the standard.

"When I was a freshman, it was the most hype thing ever when we just won a playoff game," Marion said. "That was really fun, but I also remember my senior year, before the West Ashley game, I was like, 'We have to win this.' We did, but it's not exciting if we win that, it's what we needed to do and what we have worked to do."

Marion then took the mound against Lexington and led the Gamecocks to a 6-4 win, getting all but one of the 21 outs in the victory before hitting his pitch limit. The Gamecocks then beat Carolina Forest on the road 4-2 to book a trip to the district championship against River Bluff.

Unfortunately, that's where the storybook ending evaporated for the Gamecocks, as a red-hot Gator squad handed Sumter High a pair of losses to end their season just shy of the lower state tournament. While it wasn't the final result they wanted, Marion was proud of the journey the team took to get to that point.

"The entire team was focused throughout the entire year," he said. "We had a lot of setbacks that affected us. Even though it didn't end the way we like, it was a great way to go out."

Will was just glad he was able to give the ball to Marion in their final game of the season. The SHS ace got out to a tough start, giving up five runs in the first, but persevered to give them five innings in an eventual 8-1 loss. While it was a tough final game for the entire team, Will could also see just how far Marion and the rest of the Gamecocks have come since he took over the team in the summer of 2022.

"That's one of the most rewarding things about being a coach. You've got all of those guys that were freshmen when you took over, a lot of them were on varsity, and to watch them continue to grow, a lot of that is their work ethic and their mindset. They worked extremely hard, not just on the field but in the weight room," Will said. "Marion was kind of one of the main ones there. It was very rewarding for him and deserving for him for the amount of work he put in. Obviously, you want that storybook ending of him coming out and getting that win against River Bluff, but without him, we never would've gotten there; we still would've been stuck where we were. I'm proud of what he did with the rest of those guys through their four years of high school baseball to get back to where they were accustomed to being in years past."

Throughout his entire career at Sumter High, Marion has had one guy consistently on the receiving end of his pitches: Gavin Rivers. The duo first started playing together around the age of 10 and have been inseparable ever since. Whether they're suiting up for the Gamecocks or the Sumter P-15's, that combo has been successful, pushing each other to be great.

"Marion is probably doing something (to improve as a pitcher) seven days a week, and Gavin is probably with him five or six days a week. They have both driven each other and encouraged each other going way back," Knowl said. "It's awesome to see how they've developed and encouraged each other. It's hard to imagine Marion pitching to someone else down the road, but Gavin has helped him get to this spot, so we're so thankful for that and excited for Gavin to have the opportunity to continue his career."

SUMTER P-15'S

Throughout Marion's entire career at Sumter High, he's spent his summers pitching for the local American Legion club. His first summer with the senior team was 2023, when he was the P-15's No. 2 pitcher behind SHS teammate Chase Denton. That summer, he pitched in the postseason for the junior team, helping them win the state title. In 2024, he pitched to a 1.69 ERA, going 4-1 as the co-ace with Bryce Coulter, the former Sumter High standout who was fresh off a run to the Junior College World Series with Florence-Darlington. He then led the team with a 1.40 ERA last summer as they went 16-9. The P-15's have made the state tournament during each of Marion's three summers with the team entering this season.

This summer, Marion is trying to keep a lighter workload as he prepares for college baseball but continues to be the ace of the Post 15 staff, taking the ball to open each of their series this summer.

"I've definitely had a lot of growth through the program, so it's been great," Marion said.

FUTURE IN BASEBALL

In the fall, Marion will head to Florence-Darlington, following in the footsteps of his former Sumter High and Post 15 teammate. Bryce helped spark Marion's interest in the program, as the former SHS pitcher found a ton of success with the Stingers and was able to make the jump to The Citadel, where he helped the Bulldogs win the Southern Conference and earn a trip to the Atlanta Regional of the NCAA postseason. Marion will look to follow a similar path.

"I'm really excited to go there," Marion said of Flo-Dar. "There's going to be a lot of competition there, so I'm going to have to work hard to earn my spot, but I think it'll be a great experience for me. I'll get to learn a lot, and I won't be too far away from home."

Will expects his ace to continue to blossom at one of the powerhouses of junior college baseball.

"Once he gets in there, that velocity is going to increase, and that'll only make his changeup that much better. He kinda tinkered with some stuff on his curveball with (SHS pitching coach Andrew) Twitty at the end of the year, so his curveball got a little better, so he really had four pitches. I'm really excited to see what's going to happen.

"The sky is the limit for him. I know how hard he's going to work, so he's going to get in with those guys and he's only going to get better."

Wherever baseball continues to take Marion, the Davis family will continue to savor the experience of watching their star continue to shine brightly.

"For us, it's been an entire family affair. It's something we've done as a family, watching him, so we're just very thankful for the years we've been able to do this with him, and we're excited for what's down the road," Knowl said. "Something that I've realized is how folks have rallied around Marion has been a tremendous encouragement, from our family, extended family, friends, teammates and his coaches, how they all want to see him succeed, are so proud of him and communicate that to him, it's a huge encouragement to him and to us. It's been kind of like we've been a family for 10 years, getting the privilege to watch these young men play, and we're just filled with gratitude for that. We're thankful to have those memories for a lifetime."
