Alberto Callaspo is ready to start for Angels

Alberto Callaspo, limited last week to two pinch-hit appearances because of a hamstring pull, Monday ran at 100% and Angels Manager Mike Scioscia said the third baseman will probably start Tuesday night.

With Callaspo returning, the Angels recalled reliever Michael Kohn from triple-A Salt Lake and returned infielder Andrew Romine to Salt Lake, a move that boosted their pitching staff from 11 to 12 players.

Kohn opened the season with the Angels but appeared in only five games, compiling a 4.91 earned-run average, before being sent to Salt Lake on April 10, a demotion that surprised the 24-year-old right-hander who was 2-0 with a 2.11 ERA in 24 games in 2010.

“It’s a business, you have to throw well to stay here, and I didn’t throw to my abilities,” Kohn said at the time. “I have to get back to attacking the zone.”

He appeared to do that in Salt Lake, where he was 1-1 with a 2.67 ERA and seven saves in 28 games. He led Salt Lake relievers with 42 strikeouts, and he did not give up a run in his last 11 appearances.

“He’s had a much more consistent delivery and breaking ball,” Scioscia said of Kohn, who was in uniform for Monday night’s game. “I think he feels much better about where his game is now, and hopefully that will translate into him coming up here and doing what he’s capable of doing.”

Romine started two games and appeared in one other for the Angels, collecting one hit in seven at-bats.

Old guys rule

No manager in baseball has more job security than Scioscia, who is under contract through 2018, but that doesn’t mean Scioscia, who is 52, wants to manage in the year 2039, when he is 80.

That’s why Scioscia marveled at the sight of 80-year-old Jack McKeon, who took over as Florida’s interim manager Monday, behind the cage as the Marlins took batting practice in Sun Life Stadium.

“I can’t imagine managing at 80, but the job he did in 2003 was incredible,” Scioscia said, referring to McKeon leading the Marlins to a World Series victory after taking over in May that season.

“He has a great passion for the game, and I’m sure he has the energy to do it. He’s just oozing with common sense.”

Scioscia didn’t necessarily see Florida’s upheaval — Edwin Rodriguez resigned as manager Sunday, and the Marlins lost 20 of 22 games before Monday — as an advantage for the Angels.

“We have enough on our own plate,” Scioscia said. “You really need to worry about your own team, your own house. For me, that dissolves any distractions.”

Short hops

Ervin Santana will look to end a losing streak at three games Tuesday night when he opposes the Marlins. The right-hander is 3-7 with a 4.35 ERA in 15 starts, but the Angels have scored a total of eight runs in his seven losses, and he has received three runs of support in his last three starts combined. Santana has thrown six innings or more in 13 of his starts. … Favorite line from a Twitter account called @FakeJackMcKeon, which poked fun all day at the Marlins’ new/old 80-year-old skipper: “What’s with all the hate with this LeRon Ellis fella on the Heat?”
