Pavano struggles in start against Orioles

FORT MYERS, Fla. -- Orioles left-hander Wei-Yin Chen tossed five strong innings, and Wilson Betemit and Chris Davis homered to lead Baltimore to an 11-1 win over the Twins on Thursday at Hammond Stadium.

Chen allowed just one run on four hits over five innings in his fourth Grapefruit League outing. The Taiwan native has a 3.00 ERA this spring.

Twins right-hander Carl Pavano didn't fare as well, surrendering six runs on eight hits over four innings.

"It was a dead day really," Twins manager Ron Gardenhire said. "We played about six or seven good ballgames in a row or so, but today was really dead. Carl didn't really have much on the ball today and did the best he could."

The Orioles got on the board early, as Xavier Avery doubled to lead off the game and later scored on an RBI groundout from Nick Johnson.

Minnesota came back with a run in the bottom of the first, as Ben Revere doubled and scored on an opposite-field double from Joe Mauer. Mauer went 2-for-3 on the afternoon to raise his average to .313 in Grapefruit League play.

The Orioles scored two runs in the second, when Ryan Flaherty provided a two-run triple. Baltimore tallied two more in the third coming on a two-run homer from Betemit.

Avery picked up his second double off Pavano in the fourth to score Flaherty, who singled earlier in the frame.

Davis opened the sixth with a solo homer off Twins closer Matt Capps for his first homer of the spring. Robert Andino added an RBI double in the seventh off left-hander Glen Perkins and scored on a single from Johnson.

Up next: Left-hander Francisco Liriano is set to start against the Yankees at Steinbrenner Field on Friday at 12:05 p.m. CT. The game can be seen live on MLB.TV. Liriano has been excellent this spring, posting a 2.77 ERA with 18 strikeouts and two walks allowed over 13 innings pitched. Right-handers Alex Burnett, Jeff Manship and Jared Burton are also scheduled to pitch for the Twins. Right-hander Ivan Nova starts for New York.
