The Oakland A's reinstated left-handed pitcher Sean Doolittle from the 15-day disabled list and optioned right-handed pitcher Angel Castro to Triple-A Nashville, the club announced today.
Doolittle missed all of Spring Training and started the season on the 15-day disabled list with a strained left rotator cuff. He began his rehab assignment with Single-A Stockton May 14, was transferred to Double-A Midland for one game on May 19 and moved to Triple-A Nashville May 22 for his final two appearances. Doolittle had a loss and a 9.00 ERA in five rehab appearances overall. He allowed five runs on eight hits in 5.0 innings but did not walk a batter while striking out five.
Castro was selected from Nashville May 8 and did not allow a run in three of his four relief appearances with Oakland. He compiled a 3.00 ERA but allowed six hits in 3.0 innings for a .462 opponents batting average. Castro was 0-1 with a 3.79 ERA in six games, two starts, with the Sounds.
