Darrell Rasner earned his chance. Now, with the starting pitching taking its lumps at Yankee Stadium, he needs to earn a win.

The young right-hander will make his first start of the season on Sunday against Baltimore, after injuries to Chien-Ming Wang and Jeff Karstens dropped the fifth starter's role into his lap. He'll need to keep the momentum going for the Yankees, who snapped a two-game skid on the strength of Alex Rodriguez's walk-off grand slam Saturday afternoon.

For Rasner, it's an opportunity he wasn't projected to have heading into the spring -- but one he's quick to embrace.

"It'd be a waste of time going into camp if you didn't feel like there'd be a chance," Rasner said. "I always have that outlook -- go in, do my best, and leave a good impression where they feel comfortable with me."

The Orioles counter with their ace, Erik Bedard. The lefty was 15-11 with a 3.76 ERA in 2006, but struggled Opening Day, spotting the Twins 10 hits and six runs in 4 2/3 innings.

Pitching matchup
BAL: LHP Erik Bedard (0-1, 11.57 ERA)
Bedard was 1-0 in two starts against the Yankees last season, striking out 14 in a combined 12 innings. For his career, the lefty is 2-3 with a 4.98 ERA against New York, though he has never won at Yankee Stadium.

NYY: RHP Darrell Rasner (3-1, 4.43 ERA in 2006)
Rasner is making just the fifth start of his career, and his first for the Yankees this season. One of those five starts came last September against the Orioles, when he was tagged for five runs in 2 1/3 innings. Rasner finished Spring Training with a 4.86 ERA in five games, including two starts.

Player to watch
Outfielder Nick Markakis drilled a solo homer to open the scoring in Baltimore's 10-7 loss Saturday. The second-year outfielder is perfect in two career at-bats against Rasner, with a single and a double.
