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

Sent to Triple-A
The Athletics optioned Gelof to Triple-A Las Vegas on Sunday.
Analysis
The 25-year-old didn't make his season debut until July 4 while recovering from a wrist fracture and a stress reaction in his ribs, and he's been demoted after going 2-for-25 at the plate to begin his time with the Athletics. Gelof should have a decent chance of returning to Sacramento later in the season, assuming he can get back on track at Triple-A.

Stat Review
How does Zack Gelof compare to other hitters?
This section compares his stats with all batting seasons from the previous three seasons (minimum 400 plate appearances)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.
* Exit Velocity and Barrels/PA % are benchmarked against 2019 data (min 400 PA) and Hard Hit Rate is benchmarked against last season's data (min 400 PA). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

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.

Latest Fantasy Rumors
No timeline for return
Gelof was pulled back from his minor-league rehab assignment due to a rib injury and doesn't have a timetable for 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 this is a completely different injury from the wrist injury that sidelined Gelof for the first month of the season. That was the result of being hit by a pitch during spring training, which led to 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 a return to action.
