The 22-year-old was appearing in his second Major League game when Rangers reliever Tanner Scheppers hit him with a first-pitch 96-mph fastball with the bases loaded.
He left the game immediately.
"I was inside when I saw it; it wasn't pretty," Houston starting pitcher Erik Bedard said Wednesday. "I saw him when he came back here, and he was a little dazed. I feel for him. You never want to get hit in the face. Hopefully he comes back as soon as he can."
