Blake Walston, a promising left-handed pitcher for the Arizona Diamondbacks, will undergo Tommy John surgery, sidelining him for the entire 2024 season. Manager Torey Lovullo expressed disappointment over the injury but emphasized the importance of the long-term recovery process. Meanwhile, right-handed pitcher Kendall Graveman is set for an aggressive bullpen session to assess his back tightness.

Roster updates saw pitchers Tommy Henry and José Castillo reassigned to minor league camp, while infielder Grae Kessinger was optioned to Triple-A Reno. Lovullo acknowledged the tough decisions made regarding position players, alluding to the competitive nature of the Diamondbacks' roster. Garrett Hampson, a versatile player with substantial MLB experience, is expected to have increased opportunities as he adjusts to various positions including outfield and shortstop, providing depth in the lineup.
