LOS ANGELES -- Jonathan Broxton, the embattled All-Star closer for the Los Angeles Dodgers, was sent for an MRI exam on his right elbow after finally admitting to team officials on Wednesday morning that he has been experiencing discomfort.
Manager Don Mattingly said no determination will be made on whether to place Broxton on the 15-day disabled list until the results of that exam are known.
Broxton, who apparently already had left Dodger Stadium to undergo the exam, wasn't available for comment.
"He came in today complaining about some stuff," said Mattingly, who wasn't sure how long Broxton had been experiencing discomfort. "I told him it was honorable that he wanted to pitch through that, but that in the end, it doesn't do him any good. It's not fair to him, and it's really not fair to anybody else, either."
With Broxton sidelined, Vicente Padilla will be the team's first-choice closer for now.
Broxton, who lost the closer's role in the second half of last season after making the National League All-Star team for the second time, has been shaky again this year after being given the job back to start the season. He was unavailable for a save situation April 27 in Florida because he didn't feel right playing catch.
Then, after he pitched a perfect ninth inning to record a save Monday night against the Chicago Cubs, a tentative-looking Broxton walked two of the first three batters he faced in a tied game Tuesday night, and Mattingly immediately pulled him with one out in the ninth.
"[Pitching coach Rick Honeycutt] and I were looking at tape," Mattingly said. "The way the ball was coming out, we felt like something was wrong. We were going to bring him in this morning, but [trainer] Stan [Conte] came in and said Brox came in talking about pain. Brox actually came in with him and told us what was going on.''
Broxton is 1-2 with a 5.68 ERA in 14 appearances -- converting seven of eight save chances. The six-year veteran, who had a career-high 36 saves in 2009 and dropped to 22 last year, has never been on the disabled list since making his big league debut July 29, 2005.
Mattingly said that if Broxton goes on the DL, the team likely will recall reliever Kenley Jansen, who was optioned to Double-A Chattanooga on Sunday.
