Yu Darvish pitched through pain

ARLINGTON, Texas -- Rangers manager Ron Washington confirmed Tuesday what ace Yu Darvish had alluded to before his final two starts of the season -- that the pitcher was dealing with a physical issue late in the season.

Washington didn't divulge any more information.

"I don't think I can get into that," Washington said. "I'll let y'all talk to people above me and the medical staff and let them get into that.

"I can say this: He never said that it was an issue. Yes, he had something, but he never said it was an issue."

Darvish was unable to get out of the sixth inning in his last three starts. He threw only 84 pitches in a start Sunday against the Los Angeles Angels as Washington gave him a quick hook with the tying run on base and Josh Hamilton coming up.

Darvish threw his fastball only 34 percent of the time against the Angels. His fastball velocity was down to an average of 91.7 mph in his last two starts, according to FanGraphs.
