GOODYEAR, Ariz. -- Dan Haren doesn't exactly know how to explain it, but he pitched with a "dead arm" against the Indians on Saturday at Goodyear Ballpark.

But Haren, who says he gets the same feeling every spring, was still able to weather it and toss five innings, allowing two runs on four hits in the Angels' 2-1 loss.

"It just feels like you don't get as much whip on the ball as you usually do," Haren said. "There's a certain sound you hear when you throw a ball real well, and you don't hear that sound. It's weird. Nothing hurts, but it's almost like you can't get loose. Your arm is just moving slower."

Haren was actually slated to throw four innings on a 60-pitch limit, but he needed just 48 pitches to get through five frames. He was so efficient that he had to get extra work in after his outing.

"They were very aggressive and swinging a lot, so I went out there going more for a pitch count rather than innings," Haren said. "I wanted to get to 60, so I threw 10 in the bullpen. I'm right where I want to be."

Bourjos scratched with tightness in right hip

GOODYEAR, Ariz. -- Center fielder Peter Bourjos was a late scratch from the lineup before Saturday's 2-1 loss to the Indians after experiencing some discomfort.

He went to see team doctor Lewis Yocum and was officially diagnosed with tightness in his right hip. Bourjos is listed as day-to-day.

"It's something he's played with the last few years," said Angels manager Mike Scioscia. "We anticipate he's OK."

Bourjos was originally slated to start in center and bat third. He was replaced by Jeremy Moore, who started in right field and batted eighth. Reggie Willits shifted over from right field in Bourjos' absence.

The injury left the Angels with only one expected regular-season starter in the field -- Jeff Mathis got the start behind the plate.

Callaspo starts at DH, may return to field soon

GOODYEAR, Ariz. -- Third baseman Alberto Callaspo, who has been dealing with a sore right shoulder, started at designated hitter against the Indians in Saturday's 2-1 loss, singling in four at-bats, and could see a return to the infield by the middle of next week.

"He's going to take infield today, and so we're not seeing anything that will keep him from playing in the field after the off-day Tuesday or Wednesday," said Angels manager Mike Scioscia. "So he's fine. There's no rush. He's been doing aggressive defense, but hasn't been throwing."

Callaspo was originally expected to return to the field earlier this week, but the Angels wanted to be cautious with his shoulder, which became sore during winter ball in the offseason.

The 27-year-old infielder hit .249 with two home runs and 13 RBIs in 58 games with the Angels last season after being acquired in a trade with the Royals that sent Sean O'Sullivan and Will Smith to Kansas City.
