Closer J.J. Putz was placed on the 15-day disabled list with right elbow tendinitis, but Putz and General Manager Kevin Towers are hopeful he'll be ready to come off the disabled list immediately after the All-Star break.

Putz, who said the elbow was aching after he worked three consecutive games last week against the Royals and Tigers, underwent tests that showed only swelling in the back of his elbow, Towers said.

Towers said Putz was injected with cortisone, which would have sidelined him for at least five days, so the club placed him on the disabled list with the hope that he'll be ready to return when the All-Star break concludes July 15.

"I think we realize," Towers said, "that we've got three months left to go and it's better to have him closer to 100 percent than 70 percent and trying to grind though it."

Putz has had elbow problems in the past - he had surgery for a bone spur in 2009 - but tests showed no major issues, Putz said.

"I don't really know the technical medical part of it, but structurally as far as the major stuff, ligaments, everything is fine," Putz said. "The plan is to be back right after the break. With the break I'll only end up missing around 10 games."
