Angels’ rotation plans are up in the air

The Angels hope the All-Star break, which starts Monday, will provide a healing opportunity for a starting rotation hit hard by injuries and inconsistency.

Dan Haren (back) and Jerome Williams (respiratory issue) are on the disabled list, and Ervin Santana (4-9, 5.75 earned-run average) has frequently struggled.

But before that much-needed midseason intermission arrives, the club had another hole in that rotation to fill.

Left-hander Brad Mills, called up from triple-A Salt Lake, will start Sunday against Baltimore in place of Haren, who went on the disabled list Thursday. Mills will pitch on three days’ rest.

But the starting pitching decisions don’t end there for Angels Manager Mike Scioscia, who doesn’t yet know what his currently two-deep rotation, headed by Jered Weaver and C.J. Wilson, will look like after the break.

In fact, Scioscia will have to wait to decide that until after Tuesday’s All-Star game, in which both Weaver and Wilson could pitch — and, in Weaver’s case, perhaps start. Scioscia said he doesn’t expect either to pitch for more than an inning and that it shouldn’t be an issue.

He said he should know by Wednesday who will be starting when the Angels begin the second half of their season with a seven-game trip that starts Friday in New York. They will play three games against the Yankees and four against the Tigers in Detroit.

Scioscia did say that Williams, who was hospitalized after having difficulty breathing following a June 18 start, would return to the rotation after the break. Williams made two minor league starts and said he’s feeling better. “I try to work on my breathing and just not panic,” he said.

Jepsen sharp

Reliever Kevin Jepsen was recalled from Salt Lake before Thursday’s game against Baltimore and in two appearances entering Saturday, the right-hander had tossed two scoreless innings.

A small sample size, sure, but Scioscia was impressed.

“He’s throwing the ball as well as we’ve ever seen him,” Scioscia said.

Jepsen was a primary setup man in 2009 but has struggled with injuries and inconsistent performance. He had two stints with the team in 2011 before a right knee injury cut it short.

“I’m just trying to get guys out on a consistent basis and trying not to fall into a pattern of trying to change something every day,” Jepsen said earlier this week. “My velocity is good, the knee is great.”

Line drives

Mark Trumbo’s home run in the Angels’ 3-2 loss to Baltimore on Friday was the 50th of his career in his 232nd game, making him the fastest to reach 50 home runs in club history. Tim Salmon held the previous mark, hitting his 50th home run in his 245th game.
