Hamilton, who missed five games because of ocular keratitis, which caused some vision issues for him, said he felt fine and that his eyes had nothing to do with the mistakes.
"I went to get it and it went right past me," Hamilton said of the single that rolled under his glove in the first. "I'll go back and try to look at the video. It wasn't there. The ball in the gap, I went to a spot that I thought it was going to be and it took off."
Hamilton said he "felt great" and that wasn't the reason for the mistakes. The team as a whole struggled to get things going Wednesday and didn't play a crisp game in a 9-3 loss to the A's that pulled Oakland to within three games in the AL West.
"What are you going to do? It is what it is," Hamilton said. "You don't try to have games like that, but they happen. Personally, I'm not going to give in or put my head down or start crying or collapse all over myself. The team's not going to do that, either. We'll come back tomorrow, we've got a 1 o'clock game tomorrow and we'll go get some rest."
At the plate, Hamilton was 0-for-4 with two strikeouts. The Rangers had five hits as a team and scored all three runs in the first two innings.
