Casas was invited to Boston's major-league spring training Saturday.
Casas performed well at Double-A Portland in 2021, slashing .284/.395/.484 with 13 homers, 57 runs, 52 RBI and six stolen bases across 77 games. He was rewarded with a promotion to Triple-A Worcester for the final week and a half of the minor-league season, and he'll now get a chance to work with the big-league coaching staff during spring training for a second straight year. The 22-year-old is unlikely to begin the 2022 campaign with the major-league squad but will likely be in the mix to debut at some point this year if he performs well in Worcester.
