Athletics Expected to Promote Top Prospect Luis Morales

The Oakland Athletics are expected to promote pitching prospect Luis Morales to the major leagues ahead of their series opener against the Arizona Diamondbacks. Morales, ranked as the A's No. 3 prospect and 80th overall by MLB Pipeline, has shown promise with a 3.73 ERA and 107 strikeouts over 89 1/3 innings this season between Double-A and Triple-A. Originally a starter, Morales has recently transitioned to a multi-inning relief role to manage his workload, posting a 2.00 ERA in nine bullpen appearances at Triple-A. His fastball can reach up to 99 mph, complemented by a plus slider and an improving changeup, making him a strong swing-and-miss pitcher. The move follows the trade of flamethrowing closer Mason Miller and left-handed pitcher JP Sears to the Padres, which opened roster spots and potentially a rotation slot for Morales. While it is unclear if Morales will start or relieve in his major league debut, the Athletics view him as a possible future starter who could impact their rotation as early as next season.
