Orioles designated hitter Pedro Álvarez left Thursday night's game with a hamstring "spasm/cramp," manager Buck Showalter said.
Showalter relayed that head athletic trainer Brian Ebel believes it's "just a cramp" and that Álvarez could have and would have continued, but was removed as a precaution.
"Just didn't want to take a chance with it," Showalter said. "The first time we had a little humidity here. I'm hoping that's what it was, but we'll see what it's like tomorrow."
Álvarez legged out a ground ball and beat the throw to first on an attempted double-play in the fourth inning, a frame in which the Orioles scored four times en route to a 9-6 lead.

But when Álvarez's spot came up next, Anthony Santander came up in his place and hit an RBI single.
With Mark Trumbo back in the fold, Álvarez has recently been relegated to a platoon DH role after some attempts to install him at third base. He was batting .200 at the time of his exit, but also has seven home runs and is walking at a higher rate than in previous seasons.
Any long-term absence from Álvarez would hurt the Orioles from a production standpoint, but it would add flexibility on either their bench or their pitching staff ahead of Saturday's doubleheader.
