Wilson exits with tight hamstring in Texas' loss

Starter tosses two innings, feels fine after finishing in bullpen

SURPRISE, Ariz. -- Rangers starter C.J. Wilson left the game after two innings because of tightness in his left hamstring in a 6-5 loss to the Cubs on Saturday in Surprise.

Wilson finished his work by throwing 25 pitches in the bullpen. The Rangers still expect Wilson to be on the mound for Opening Day against the Red Sox on Friday at the Ballpark in Arlington.

Wilson allowed three runs on four hits and finished the spring with a 5.06 ERA. He walked none and struck out one. Brett Tomko took over and allowed three runs in five innings, although he retired 11 of the last 12 batters he faced.

"I was just a little tight from sprinting yesterday," Wilson said. "I just didn't loosen up, and after we had that long first inning batting, it was tough to get it going. But I'm fine. Today I knew my legs were tight, so I knew I couldn't put much on the ball. So I was working on my offspeed stuff."

Reliever Mark Lowe had his best outing of the spring, retiring the side in order in the eighth after taking over for Tomko.

Cubs starter Andrew Cashner, who was officially named to the rotation on Saturday, allowed five runs in the first inning. The big blow was a two-run home run by Mitch Moreland, his fourth of the spring.

He got out of the first inning when Andres Blanco delivered an RBI single to right and then was thrown out trying to go to second on the throw to the plate. Cashner then responded by throwing four scoreless innings while retiring 11 of the last 12 batters he faced.

"The biggest thing for me today is competing after that first inning," Cashner said. "It's tough giving up a five spot in the first. The biggest thing I did was battle, and I didn't let that faze me."

Rangers up next: Right-hander Colby Lewis will make his final start of the spring at 3:05 p.m. CT on Sunday against the Mariners in Peoria, live on MLB.TV. Elvis Andrus, who is hitting .340 in his last 13 games, is expected back in the lineup after getting Saturday off. Julio Borbon also missed Saturday with soreness in his left elbow but could be back on Sunday.

Cubs up next: Opening Day pitcher Ryan Dempster will make his last start of the spring against the Rockies at 3:05 p.m. CT on Sunday at HoHoKam Park, live on MLB.TV. Dempster is 1-0 with a 1.88 ERA in five starts this spring. He will be on the mound on Friday, April 1, when the Cubs open the season against the Pirates at Wrigley Field.
