Baker said Alvarez has had the problem for about a week.
“We decided to send him to go get examined,” Baker said. “Hopefully it’s not too bad. So, we’ll see.”
Baker is hopeful that Alvarez can avoid going on the injured list.
“We don’t think so,” Baker said. “We hope not. We just have to see after he sees the doctor.”
Alvarez is hitting .253 with six homers and 27 RBIs. He hit late go-ahead homers in the first two games of the Astros’ weekend sweep of the Atlanta Braves. Alvarez, who has eight multi-RBI games, added a game-tying two-run single in the eighth inning of Sunday’s series finale.
Baker said it has not been determined if Alvarez will return for the final two games of the road series with the Rays.
