Red Sox infield prospect Mason White has been named a 2026 South Atlantic League All-Star, Minor League Baseball announced on Wednesday.
White, Boston’s fourth-round pick in the 2025 draft out of Arizona, opened his first full professional season at High-A Greenville. The left-handed hitting 22-year-old batted .270/.362/.525 with 14 doubles, three triples, 14 home runs, 42 RBIs, 36 runs scored, 31 walks, and 63 strikeouts in 68 games (282 plate appearances) for the Drive before being promoted to Double-A Portland in late July.
Among 87 hitters who made at least 280 trips to the plate in the South Atlantic League this season, White ranked 11th in slugging percentage, 12th in isolated power (.254), 13th in OPS (.887), 18th in wOBA (.388), 19th in swinging-strike rate (10%) and wRC+ (121), 25th in batting average, 31st in on-base percentage, and 32nd in strikeout rate (22.3%), according to FanGraphs.
After arriving in Portland on July 19, White closed out the season by batting .208/.333/.377 with four doubles, one triple, four home runs, 13 RBIs, 18 runs scored, two stolen bases, 20 walks, and 39 strikeouts in 33 games (129 plate appearances) for the Sea Dogs.
Overall, then, White slashed .251/.353/.480 with 18 doubles, four triples, 18 home runs, 55 RBIs, 54 runs scored, two stolen bases, 51 walks, and 102 strikeouts across 101 games (411 plate appearances) between Greenville and Portland in 2026. He posted a .255/.350/.497 line in 343 plate appearances against right-handed pitchers and a .232/.368/.393 line in 68 plate appearances against left-handed pitchers.
“Mason hits the ball really hard,” Red Sox senior director of player development Brian Abraham told MassLive.com’s Christopher Smith earlier this month. “We’ve definitely focused on the swing-and-miss a little bit. He has had a little bit of that, but it’s improved. I think that comes with pitch recognition and understanding the strike zone. Being able to handle the pitches that he knows he can drive and laying off pitches that he can’t.”
Defensively, White saw most of his playing time this year come at either second base or shortstop. Between his stops in Greenville and Portland, the 5-foot-11, 180-pounder made 48 starts at second and 47 starts at short, committing six errors in 337 total chances. He also made five starts at DH.
White, who turns 23 next week, is currently ranked by Baseball America as Boston’s No. 28 prospect. While his affiliated season is over, he was one of eight Red Sox minor leaguers selected to play for the Mesa Solar Sox in the Arizona Fall League, which begins in early October. The assignment will not only allow him to continue working on his development, but also give him the opportunity to take the field in his home state for the first time as a pro.
