In his first year with the Red Sox, pitching prospect David Sandlin emerged as one of the hardest throwers in the organization.
Sandlin was one of 90 prospect-eligible pitchers to reach triple-digits in the minor leagues this season, according to Baseball America’s Geoff Pontes. The 23-year-old right-hander accomplished that feat by maxing out at 100.4 mph with his four-seam fastball.
Acquired from the Royals for reliever John Schreiber in February, Sandlin broke camp with High-A Greenville this spring. The former 11th-round draft selection out of Oklahoma posted a 5.17 ERA (5.73 FIP) with 21 strikeouts to eight walks in his first four starts (15 2/3 innings) for the Drive before being placed on the 7-day injured list on May 14.
Due to right forearm tightness, Sandlin was sidelined for over a month and did not return to the mound until June 15. He then pitched to a 5.06 ERA (2.93 FIP) with 29 strikeouts to just three walks in his next six starts (16 innings) for Greenville before receiving a promotion to Double-A Portland on July 23. With the Sea Dogs, he produced a 5.61 ERA (5.36 FIP) with 32 strikeouts to seven walks in eight starts (25 2/3 innings) to close out the 2024 campaign.
Altogether, Sandlin forged a 5.34 ERA and 4.78 FIP with 82 strikeouts to 18 walks in 18 total starts (57 1/3 innings) between Greenville and Portland this season. Opposing hitters batted .269 against him, though his 33.2 percent strikeout rate, 15.9 percent swinging-strike rate, 7.3 percent walk rate, and 3.10 xFIP were among the top marks for those in the system who eclipsed the 50-inning plateau, per FanGraphs.
“David did join the Fuego club,” Red Sox director of pitching Justin Willard said of Sandlin reaching triple-digits when speaking with NESN’s Tom Caron and The Boston Globe’s Alex Speier on NESN’s ‘310 To Left’ Podcast last month. “He hit 100 and was sitting 96. It’s unreal stuff. Really excited about his development this year, again really raising the floor to give him a shot to be an elite starter.”
To complement his high-octane heater, Sandlin mixes in three other pitches: an 85-88 mph sweeping slider, an 86-90 mph splitter, and a 77-81 mph curveball. The athletic 6-foot-4, 215-pound righty throws those offerings from a three-quarters arm slot while incorporating a high leg kick into his delivery.
Sandlin, who turns 24 this coming February, is currently regarded by Baseball America as the No. 11 prospect in Boston’s farm system, which ranks third among pitchers in the organization. He is projected to return to Portland for the start of the 2025 season but will need to show that he can go deeper into his outings to fully tap into his starter potential.
