While the Orioles are hoping their offense won't have to play without slugging first baseman Chris Davis for very long, the Angels are throwing a bit of a rotation curveball at them for the finale of their four-game series Sunday.
Jerome Williams will make his first start of the 2013 season, taking the place of Garrett Richards, who shifts to the Angels' beleaguered bullpen. Williams squares off against Jason Hammel, the Orioles' Opening Day starter, with the host Angels hoping to even up the series.
Davis' status is of concern for the Orioles, as the American League Player of the Month for April injured his right knee Friday night. Preliminary indications after a MRI scan on Davis' knee are good, Orioles executive vice president of baseball operations Dan Duquette said on Saturday.
"It doesn't look like Chris Davis will go to the DL," Duquette said.
While Davis remains day-to-day, it'll be up to the rest of the Orioles to keep up the momentum from their victory Saturday to the series finale on Sunday.
The Angels changed things up by inserting Williams into the rotation, where he made 15 starts among 32 total appearances in 2012. He pitched six innings of one-run ball in relief during the Angels' 19-inning loss to the A's on Monday.
"It doesn't matter if I'm starting or relieving. I'm still going to do the same thing," Williams said.
Williams hasn't allowed an earned run in his last four appearances (13 innings), and this opportunity back in a starting role is an indication of how well he's thrown.
"I feel like they have confidence in me, but my mentality is not going to change," Williams said. "I still have that mentality of what I had in the bullpen, which is to go out there and pitch with attitude."
Hammel, who made his first career Opening Day start, will be making his seventh start of the season and his fifth on the road. Hammel is 0-3 with a 7.02 ERA (16 2/3 innings, 13 earned runs) in four career games (three starts) against the Angels, including going 0-2 with a 9.90 ERA in two starts last season.
Orioles: Pearce fills in at first
With Davis out of the lineup Saturday, Steve Pearce got the start at first base, going 3-for-4 with the game-winning RBI. Davis had started the first 30 games of the Orioles' season at first.
Pearce, whose first 10 starts of the season all came as designated hitter, has 90 appearances at first base in his parts of seven seasons in the Majors.
Ryan Flaherty, who filled in at first once Davis left Friday's game in the fifth inning, started at second Saturday.
Angels: Bullpen side of shuffle
A big part of the reason the Angels made the shift to put Williams in the rotation was to get Richards' arm in the bullpen. That didn't work out well the first time out, as Richards gave up the winning run in the 10th inning on Saturday.
But Angels manager Mike Scioscia said bringing Richards over to the bullpen side will help the relief situation overall.
"We definitely need to look at shuffling some things around to get a deeper look in our bullpen. There's no doubt about that, first and foremost," Angels manager Mike Scioscia said. "Garrett Richards' arm in the bullpen is definitely a power arm that we hope can take some of the pressure off the guys that are pitching a lot there."
