ANAHEIM -- When right-handed pitcher Michael Kohn took his place in the Angels clubhouse, he found his locker located right next to Ryan Madson's.
Kohn, like Madson, missed the 2012 season because of Tommy John surgery. On Friday, both of them made significant strides. Kohn -- who has already appeared in five games for Triple-A Salt Lake this season -- was recalled to the Angels, and Madson faced four hitters in a simulated game -- marking the first time he has faced live batters.
Friday's simulated game was not the best Madson has looked on a mound since his surgery, but manager Mike Scioscia knows the reliever is making progress.
"Not quite as crisp as when he threw his bullpen in Minnesota, but the fact that he's facing hitters is important, and I thought his velocity was good," Scioscia said. "I didn't think his command was quite where it could have been, [he] threw some good changeups. There's no doubt if you look back to where he was in the last two weeks, he's moved ahead."
Madson's said his mechanics were off, but more importantly, his arm felt "fine."
"It feels like Spring Training to me now, feels like early Spring Training," Madson said. "But it'll come real quick."
Madson threw about 20 pitches in the bullpen then threw between 20 and 30 to Hank Conger, J.B. Shuck, Luis Jimenez and Andrew Romine.
"I'm not 100 percent; I don't feel normal, but I'm close to it," Madson said.
Madson plans to play catch Saturday and does not know what his next step -- whether it be a bullpen, rehab assignment or another simulated game -- will be.
Callaspo hits DL; Kohn added to bullpen
ANAHEIM -- When Alberto Callaspo first felt tightness in his right calf, the Angels were hopeful it was something that would subside in a few days.
That was a over a week ago, and Callaspo simply has not been making enough progress for the team work around the injury, and he was placed on the disabled list prior to Friday's game against the Tigers.
"Alberto wasn't making enough progress to project he was going to be able to play here in the next three or four days," manager Mike Scioscia said. "He'll be ready in eight or nine days."
Callaspo, whose stint on the DL will be backdated, is hitting .273 in nine games this season.
The Angels recalled right-handed pitcher Michael Kohn from Triple-A Salt Lake to assume the open roster spot.
"He's throwing the ball better than anybody down there right now," Scioscia said. "There's a role for him and hopefully he's going to come up here and get some outs."
Kohn's presence is much needed in the Angels' bullpen, which is already without Garrett Richards (in starting rotation), Ryan Madson (DL) and Kevin Jepsen (DL). Relievers have had to pitch a lot of innings this season because starters haven't gone deep into games.
Kohn pitched 4 1/3 innings in Triple-A. He had one save, seven strikeouts and didn't allow a run.
In 2011, Kohn appeared in 14 games for the Angels, pitching 12 1/3 innings.
"Especially after missing 2012 with Tommy John, it's very good to be back," Kohn said. "It's been a long road recovering, but it's well worth it."
The right-hander is unsure of what his exact role will be, but his approach will be simple and direct.
"Whatever role they want me in, I'm just going to try to get outs and do it to the best of my ability," Kohn said.
Injured Jepsen is still not throwing
ANAHEIM -- Angels reliever Kevin Jepsen, who was placed on the 15-day disabled list Saturday with a strained right lat muscle, has not picked up a baseball since and is hoping treatment and rest will alleviate the pain.
"I haven't been trying to recreate the pain or anything like that," Jepsen said. "I've just been trying to let it calm down, not moving it."
Jepsen plans on letting the medication run its course and is unsure when he will resume throwing.
"Right now, there's no real telling as far as what's going to happen," Jepsen said.
In 3 2/3 innings this season, Jepsen allowed four earned runs while trying to pitch through the pain.
• Albert Pujols was Friday night's designated hitter for the fourth time in five games. This comes after the Angels had a game postponed Wednesday and a scheduled off-day on Thursday. The first baseman is dealing with plantar fasciitis.
• Prior to Friday night's game, Mike Trout was honored for winning the 2012 GIBBY (Greatness in Baseball Yearly) Award for top play. Trout was recognized for his catch in Baltimore in which he robbed J.J. Hardy of a home run.
