"It was a shot in the arm, all right. Just not the kind the Angels wanted.

Dan Haren's first start as an Angel ended abruptly in the fifth inning Monday night when a line drive off the bat of Kevin Youkilis smacked into the pitcher's right forearm.

The right-hander crouched in pain before walking off the field, his debut prematurely finished during the Angels' 6-3 loss to the Boston Red Sox at Angel Stadium.

Haren was diagnosed as having a bruise on his forearm and is scheduled to be reexamined Tuesday by Dr. Lewis Yocum, the Angels' team orthopedist.

"It hurt, but I didn't feel it hit any bone," Haren said, adding that he hoped to throw off a mound Wednesday to test the arm and make his next start as scheduled Saturday. "That was the good thing."

Boston cleanup hitter David Ortiz delivered more blows with two homers in the same ballpark where he won the home run derby exactly two weeks earlier as part of the All-Star game festivities."
