Colby Thomas

24-Year-Old OutfielderOF
Sacramento Athletics AAA
2025 Fantasy Outlook
Thomas isn't a perfect prospect, but he's big-league ready and has a chance to hit 20-plus homers with double-digit steals if he gets enough playing time as a rookie. He tallied 31 homers and 15 steals in 132 games split between Double-A and Triple-A. While his slash lines were similar and his ISO was almost identical at the two levels, Thomas' strikeout rate jumped from 18 percent at Double-A to 30.3 percent at Triple-A. His walk rate also jumped slightly from 6.5 percent to 7.3 percent, and the balls and strikes challenge system at Triple-A may have factored into both metrics going up. Given that Thomas was 23, what he did at Triple-A is more instructive for 2025 than what he did at Double-A, so don't expect him to hit north of .250. He's a quality defensive outfielder, capable of playing all three spots, and he bats right-handed, so Thomas could conceivably gain everyday playing time early this season. Read Past Outlooks

Returns to action over weekend
OFSacramento Athletics  AAA
March 24, 2025
Thomas (knee) played in Cactus League games Saturday and Sunday and went a combined 2-for-5 with a home run, an additional run and two RBI while playing 13 innings in left field.
ANALYSIS
Thomas' pair of appearances were his first since March 15, when he exited a game against the Rangers after taking a line drive off his right knee. The outfielder had already been reassigned to minor-league camp March 10, so the injury wasn't a factor in him not making the Opening Day roster. Thomas is expected to begin the 2025 season at Triple-A Sacramento.
