2025 Fantasy Outlook
After breaking out to the tune of 14 homers and 14 steals in just 69 games as a rookie, Gelof endured the dreaded sophomore slump last season. He struggled mightily with strikeouts, fanning an AL-worst 188 times, which resulted in a 56-point drop in batting average to .211. Gelof showed signs of recovery in June only to post OPS marks below .700 in each of the final three months. The Athletics had nothing to lose and kept Gelof on the field at second base, affording him the opportunity to rack up 17 homers and 25 steals across 547 plate appearances. Gelof and the rest of the A's will be playing their home games at Sutter Health Park in West Sacramento in 2025 -- home of the Triple-A Sacramento River Cats of the Pacific Coast League -- which would seem to bode well for the offense. The pressure will be on for Gelof to bounce back and prove he should be considered part of the organization's long-term future. Read Past Outlooks

May 5, 2025
The team has paused Gelof's (wrist) rehab assignment after being diagnosed with a stress reaction in his ribs, Martin Gallegos of MLB.com reports.
ANALYSIS
Gelof was sent out on a rehab stint with Triple-A Las Vegas that started Tuesday as he continues to work back from surgery on his right wrist, but he's now being bothered by his ribs. He'll be shut down from swinging a bat until he can get the stress reaction under control, likely pushing his 2025 debut to late May in a best-case scenario.

Past Fantasy Outlooks
2024
2023
Oakland was eliminated from the postseason on the second day of the 2023 season, so it remains a mystery why they let Gelof stay in the minors as long as he did rather than try to push for a prospect promotion incentive pick. Gelof began the season with 12 homers, 20 steals, and a .304/.401/.529 line in Sacramento over 69 games before coming to Oakland and hitting 14 more homers with 14 steals and a .267/.337/.504 line in the same amount of games. All in all, Gelof finished with 26 homers, 100 runs, 76 RBI, and 34 steals in 138 games. All that from someone whose ADP was in the 700's last winter. Strikeouts have been an issue as he has rapidly ascended in the system since coming out of the University of Virginia which will limit the ceiling of his batting average, but he should volume plenty in the other categories as an everyday major leaguer in 2024. His market price year over year has improved more than any other hitter.
In many organizations, Gelof might have a hard time breaking through for MLB playing time in 2023, but that shouldn't be the case in Oakland. He spent more time at second base than third base in 2022 and projects as the everyday second baseman as early as this summer, depending on how he handles a return to Triple-A. Gelof's 68.9 Contact% and 27.5 K% in the upper levels, primarily Double-A, portend initial struggles against big-league pitching. There is a slight chance Gelof could develop an above-average hit tool with plus power, but it's probably more likely he has an average hit tool with above-average power. That would equate to a useful middle infielder in fantasy, especially since Gelof is likely to hit in the middle of the lineup, but there's not a lot of upside here, given his future home park and lineup.

Latest Fantasy Rumors
No timeline for return
2BSacramento Athletics
May 6, 2025
Gelof was pulled back from his minor-league rehab assignment due to a rib injury and doesn't have a timetable for his return, according to Martin Gallegos of MLB.com.
ANALYSIS
The second baseman sustained a stress reaction in his ribs and has been shut down from swinging a bat, but the most concerning aspect of the situation is that this is a completely different injury from the one that sidelined Gelof for the first month of the season. That time, the infielder was hit by a pitch during Spring Training and suffered a hamate fracture in his right wrist that shelved him for around four weeks. This latest setback suggests Gelof doesn't have a clear timetable for his return to action.
