Dodgers Manager Don Mattingly was watching videotape of his closer, Jonathan Broxton, on Wednesday morning, seeking clues to Broxton's inability to throw strikes the night before, when team trainer Stan Conte walked into the room.

"You don't need to look at tape anymore," Mattingly said Conte told him. The reason: After repeatedly insisting he felt fine in recent days, Broxton had acknowledged a sore elbow on his right pitching arm.

A couple of hours later, there was more bad news for the Dodgers. Andre Ethier, riding a 29-game hitting streak, said he had a sore left elbow, so Mattingly scratched him from the lineup shortly before the Chicago Cubs' 5-1 win at Dodger Stadium.

Broxton's immediate future is unknown, pending the outcome of an MRI exam. But something definitely appeared wrong with the burly relief pitcher when he walked two batters on eight consecutive balls in the ninth inning Tuesday night, opening the door for a Cubs win.

"We'll find out what's going on exactly and then have a plan of attack," Mattingly said. Asked how long the elbow had bothered Broxton, who has seven saves but an earned-run average of 5.68, Mattingly replied: "He didn't really say the length of time, so I'd be kind of guessing."

Broxton, 26, struggled to explain his problems.

"It doesn't hurt when I'm throwing; it's just afterward it stiffens up a little bit," he said. "I don't think it's something serious or I wouldn't be able to throw at all."

Regardless, Mattingly said he told Broxton that while "it's honorable" that Broxton hoped to pitch through the soreness in his arm, "in the end it doesn't do him any good and it's not fair to him and it's really not fair to everybody else."
