ANALYSIS
Thomas was invited to the Athletics' major-league camp in 2020 but failed to reach the big leagues during the abbreviated season. He'll get the chance to work with the major-league coaching staff once again in 2021 and should compete for a roster spot with the Mariners at some point during the regular season. The 28-year-old slashed a combined .251/.325/.404 with 19 home runs and 108 RBI over multiple stints at the Double-A level over the last few seasons, but he'll need to work on improving his strikeout rate going forward.
