J.J. Putz threw four pitches on Tuesday night against the Los Angeles Dodgers before leaving the game with elbow discomfort. On Wednesday, the Arizona Diamondbacks put their closer on the 15-day disabled list and the prognosis does not look promising.
ESPN's Buster Olney tweeted: All signs point to J.J. Putz need a major elbow operation; at the very least, he'll be out a long time.
Putz told the Arizona Republic he felt tightness in his elbow and tingling in his arm down to his fingers.
Three-time All-Star Heath Bell will take over the role as closer for the Diamondbacks. The 35-year-old Bell has made 14 appearances this year and has a 4.73 ERA.
To replace the 36-year-old Putz on the active roster, Arizona called up 28-year-old right-handed reliever Will Harris from Triple-A Reno.
