It hasn't mattered if he's been in the starting rotation or come out of the bullpen, Jerome Williams has been a successful pitcher for the Angels this season.
Williams is 3-2 with a 3.08 ERA in six games as a starter and 1-0 with a 2.55 ERA in 10 games as a reliever.
With the Angels in need of a sixth starter because of a Saturday doubleheader, the right-hander will make his seventh start of the season on Wednesday against the the Orioles at Camden Yards.
"I think Jerome has the opportunity to be a wild card, whether he's back in the rotation or helping us with an appreciable role in the bullpen," Angels manager Mike Scioscia said.
Posting a 2.14 ERA in his last five starts, Williams will make his first start since a June 1 loss to the Astros. In that game, he allowed two runs on three hits in seven innings of work.
He took a loss to the O's in his first start of the season on May 5, allowing five runs on four hits in 4 1/3 innings.
Meanwhile, Jason Hammel (7-4, 5.18 ERA) will be on the hill for Baltimore, hoping to snap a personal two-game losing streak.
The right-hander was a tough-luck loser in his last start on Friday night against the Rays, allowing two runs on six hits in 6 2/3 innings.
Hammel retired 10 of 11 before allowing a single to James Loney and then a two-run home run to Desmond Jennings in a 2-1 loss.
"Ham was pitching as well, if not better, up until [then]," said Orioles manager Buck Showalter, who replaced his starter two outs later. "There's a fine line there in a game like that and mistakes get magnified. Ham deserved a lot better fate. It was really good to see him pitch as well as he did."
Angels: Bourjos robs Hardy
Another Angels center fielder robbed Orioles shortstop J.J. Hardy of a home run in Tuesday's game at Camden Yards.
Last year, on June 27, a likely Hardy home run was taken away by Mike Trout, who leaped off the track in Baltimore to turn in what many thought was the best catch of 2012.
It happened again on Tuesday, with Peter Bourjos, the speedy center fielder who was activated off the disabled list on Monday, making the play in straightaway center.
With one out and a runner on first in the bottom of the first inning, Hardy jumped on a Jason Vargas fastball and drove it deep. Bourjos raced straight back, all the way to the wall, timed his jump perfectly and came back with Hardy's ball in his glove.
Orioles: Casilla nursing index finger
Baltimore second baseman Alexi Casilla was out of the starting lineup for Tuesday's game against the Angels.
Casilla was caught trying to steal second base on Sunday against the Rays and jammed his right index finger in the process.
He did not play in Monday's game and tried to play catch Tuesday, but said he only threw the ball once because the finger was still too sore.
"Lexi's a little better today -- not quite where he needs to be to start -- but he's available to us to some extent," Showalter said before Tuesday's game. "The swelling is starting to go down so that's good."
• Orioles starter Wei-Yin Chen (strained oblique) threw long toss on Tuesday and will next throw from a half-mound on Thursday.
• Angels right fielder Josh Hamilton has seven home runs in his last six games at Camden Yards and nine home runs in his last 11 contests there.
