Fantasy baseball analyst Dalton Del Don rounds the bases to identify his favorite sleepers at each infield position. If you want even more sleepers, click here for his options from every MLB team.
Athletics: Zack Gelof, 2B
Gelof’s ADP has sunk compared to last year thanks to a down 2024, but he’s one season removed from posting a 132 wRC+ as a 23-year-old. Gelof has averaged 16 homers and 20 steals over just 104 games during his two years in the majors. He’s a clear batting average risk, but last season’s .201 BABIP against left-handers is sure to regress. Gelof has clubbed 20 of his career 31 homers on the road, so he’ll benefit from Oakland’s move to Sacramento.
The Oakland Coliseum ranked as the fifth-worst for RHB over the past three years, according to Park Factors. The Athletics will be moving to Sutter Health Park, which has played mostly neutral in Triple-A, but A’s hitters should benefit from their new climate and significantly smaller foul territory. The park also had a new batter’s eye installed to improve visibility. OOPSY projects Gelof to be one of only two second basemen to go 20/20 this year. He’s a sleeper available late in fantasy drafts.

Baltimore Orioles: Ryan Mountcastle, 1B
Mountcastle has lost 11 homers to Baltimore’s left-field wall over 2022-24, so he gets a boost in fantasy drafts thanks to dimension changes at Camden Yards. The Orioles are moving in their left-field wall to fix an overcorrection after moving it back before the 2022 season. The dimension changes could have a real impact, as the moved-back wall prevented 196 home runs over the last three years. Oriole Park has decreased HR for RHB by 21% (the third-most in MLB) over that span, and it’s produced the second-lowest HR/FB rate for righties since 2023. Mountcastle should return to 20+ homers in 2025.
Boston Red Sox: Trevor Story, SS
Story’s draft standing has become a discount after three straight injury-filled seasons. He remains a batting average risk, but Story could return plenty of value while hitting in Boston’s lineup. Fenway isn’t Coors Field, but it’s been MLB’s second-best hitter’s park for right-handed batters over the last three seasons. Story has been aggressive on the base paths since joining the Red Sox, and OOPSY projects 19 home runs and 27 steals while missing 20+ games. Story is a cheap way to fill middle infield late in drafts.
