"I know what the problem is: I try too hard, I think too much. I need to slow down my mind," Choo said Sunday as he returned to Cleveland's lineup against Texas after getting a game off. He went hitless in a 2-0 loss.
Choo was arrested May 2 on suspicion of drunken driving after a breathalyzer test showed he had a blood-alcohol level of .201. Ohio's legal limit is .08.
Choo said he is no longer worried about the legal problems stemming from his arrest, but is concerned with how he is regarded in both America and his native South Korea.
RED SOX: Pitcher Daisuke Matsuzaka is preparing for surgery to repair a torn ligament in his right elbow.
Matsuzaka spoke Sunday for the first time since the Red Sox placed him on the 60-day disabled list so he can have Tommy John surgery, likely this week.
"It's my first time to get an operation and all I can say is I'm very shocked when it comes to this result," Matsuzaka said through an interpreter. "I was told the ligament is torn and to fix it perfectly I need to have surgery."
White Sox: Right-hander Jake Peavy left Chicago's game against the Detroit Tigers with a strained right groin.
Peavy allowed six runs in the fourth inning, then departed. He took the loss as Detroit won 7-3.
He will be re-evaluated on today. Peavy's 2010 season ended when he injured his right shoulder on July 6.
The 2007 NL Cy Young Award winner rejoined the team on May 11 after recovering from shoulder surgery and was 2-0 with a 3.24 ERA in four starts before Sunday's game.
