Colby Thomas

After a disappointing debut season in 2025 that saw him struggle with a .225 average and limited power production, Thomas enters 2026 still searching for consistency at the plate in his second MLB campaign. Early 2026 returns have been even more concerning, with his batting average dipping to .221 through limited at-bats, though he does retain some modest upside in home runs and runs scored as he develops at the major league level. The A's prospect pedigree—highlighted by his MiLB.com Organization All-Star designation and postseason honors—suggests tools exist to justify his inclusion in some deep leagues, but fantasy managers should approach with caution given his current struggles to produce power or meaningful contributions across the statistical categories that matter. Thomas offers little in the way of reliable production for most fantasy lineups in 2026 unless he demonstrates a significant turnaround at the plate.
