OAKLAND, Calif. — Athletics ace Sonny Gray has been put on the 15-day disabled list because of a strained trapezius muscle near his right shoulder blade.

Oakland made the move Sunday, two days after Gray threw three wild pitches and walked four while retiring just 10 batters in an 8-3 loss to the Yankees. Gray is 3-5 in nine starts with a 6.19 ERA, third-highest in the AL among qualifying pitchers.

Gray said he received a shot that was half cortisone and half anti-inflammatory in his shoulder not long after exiting the game, but the condition did not get any better.

Rangers: Yu Darvish threw six scoreless innings Sunday in what is likely to be his last rehab start before returning to the Texas Rangers rotation for the first time since late in the 2014 season.

Darvish is coming back from Tommy John surgery and threw 56 of 87 pitches for strikes while pitching for Double-A Frisco.

ASROS: Outfielder Carlos Gomez (bruised left ribcage) is expected to begin a rehab assignment with Double-A Corpus Christi on Tuesday.

UMPIRE: Plate umpire David Rackley left Sunday’s game between the Dodgers and Padres after getting hit in the groin by a foul bunt attempt by Joc Pederson.

ORIOLES: Right-handed pitcher Yovani Gallardo (shoulder tendinitis) threw his first bullpen session since going on the 15-day DL on April 23.
