Oakland A's injury: Henderson Alvarez felt shoulder soreness Sunday, other updates

Oakland A's manager Bob Melvin informs beat writers (including the Sacramento Bee's Matt Kawahara) that starting pitcher Henderson Alvarez was pulled an inning early from his last scheduled rehab start for the Nashville Sounds on Sunday night after he experienced some "shoulder soreness," though "Alvarez 'feels a little better' today." He pitched five innings on Sunday.

Alvarez, who was rehabbing from 2015 shoulder surgery, will have an MRI tonight or tomorrow to determine if it's anything serious (tweets the Bay Area News Group's John Hickey), though it appears Alvarez's debut may be pushed back by at least one trip through the rotation. The club had hoped to start Alvarez against the Yankees on Friday.

A scout who saw Henderson Alvarez's outing told me trainers came out 1 inning before his last IP but stuff didn't drop off at all afterward.

This does open the door to Jesse Hahn joining the rotation in place of Eric Surkamp, and likely saves either Sean Manaea or Kendall Graveman from demotion for now. Hahn is eligible to be called up as soon as Wednesday, though current top starter Rich Hill is scheduled to face the Texas Rangers that day. From the San Francisco Chronicle's Connor Letourneau:

When asked why Jesse Hahn is no longer making his Tues. start in Nashville, Melvin said he'd have some news later on the A's rotation.

2B Jed Lowrie hit off tee Sunday, now doing some work on defense during batting practice. #Athletics hope his stay on DL will be brief.

Lowrie is eligible to come off the DL on May 25.
