On Saturday, he used new tinted contact lenses -- they made his blue eyes appear red -- and didn't get the results he wanted. Hamilton, the designated hitter in the Rangers' 14-5 loss to the New York Mets, was 0 for 4 with four strikeouts. He saw 17 pitches and 15 of them were strikes. After his first three strikeouts, he took the contacts out and tried to hit without them. It didn't change his fortune.
Hamilton is now hitting .113 (6 for 53) in day games in 2011 and .377 at night.
"I'd be batting .600 if I could figure out how to hit in day games," Hamilton said. "It's frustrating for me knowing obviously I could help my team in a big way. I'm there with runners in scoring position and stuff like that and I'm up there looking lost trying to swing the bat. I'll figure it out."
Hamilton said he probably won't use the contact lenses again, complaining that his depth perception was off.
"I was late on pitches at 86 miles per hour," Hamilton said. "That's not normal stuff. It's just like I was hitting with my glasses on in batting practice."
But Hamilton said he found a different pair of sunglasses, which he had used last season. He plans to give those a try.
Manager Ron Washington was asked if Hamilton was experimenting with ways to get his vision right.
"You never experiment when you compete, not at the major league level," Washington said. "Yeah, he wore contacts. You have to decide if they worked."
Washington said he hasn't determined whether Hamilton will play in Sunday's game against the Mets, which starts at 2:05 p.m. CT.
