Oakland A's place Sean Doolittle on disabled list with strained left shoulder, recall Angel Castro

The Oakland Athletics returned left-handed reliever Sean Doolittle to the 15-day disabled list with a strained left shoulder retroactive to May 28 and recalled Angel Castro from Triple-A Nashville, the team announced. Doolittle was activated last Tuesday from a slight left rotator cuff tear, and made one appearance on Wednesday, striking out two.

Sean Doolittle spoke to beat reporters before Saturday night's games, and said that an MRI revealed no tear:

Doolittle got MRI this morning. No tear, just inflammation in shoulder blade and into shoulder capsule a bit.

Just before the announcement, MLB.com's Jane Lee tweeted details of Doolittle's troubles on Friday:

Doolittle, who appeared uncomfortable playing catch yesterday and didn't participate in PFP, could be headed back to DL.

It is not known whether Doolittle's velocity issues, where he only once reached 90 miles per hour on his fastball, were related to this injury.

Angel Castro returns to the A's after he was sent down for Doolittle on May 26. With the Athletics, Castro made four appearances totaling three innings of work, with three strikeouts, three walks. and one solo home run allowed. He made one appearance for Nashville during his brief return, earning the save against the Sacramento River Cats in one inning while striking out one.
