MILWAUKEE -- Zach Braddock struck out all five hitters he faced Thursday in a solid start to his Minor League rehabilitation assignment, but the Brewers were unsure as of Friday afternoon when he would be ready to rejoin the big league bullpen.

Braddock was placed on the 15-day DL on May 3 with a sleep disorder and is eligible to return on Monday. But that's the day the Brewers begin a bizarre, four-game West Coast road trip that concludes with a night game on Thursday in San Diego. The Brewers expect to return to Milwaukee at about 5:30 a.m. CT on May 20 and play the Rockies at Miller Park that night.

The scenario is not exactly conducive to someone having trouble sleeping.

"I don't know if we'll have him fly there, or, if he's still fine, activate him when we get back," manager Ron Roenicke said. "We're going to rely on what the doctors have to say about him."

Braddock was a key bullpen piece in 2010, when he posted a 2.94 ERA and was able to retire both left-handed and right-handed hitters. The Brewers currently only have one left-hander in the bullpen, Mitch Stetter, and he is at his best when he faces only lefty hitters.

Roenicke would prefer to carry seven relievers instead of the Brewers' current eight, and a healthy Braddock would help.

"Eight relievers is not ideal," Roenicke said. "It helps if that guy in the bullpen is a lefty and can run through some right-handers. ... So Braddock is important, because last year when he was throwing well, it didn't matter who was hitting."

Kintzler heads to DL with triceps tendinitis

MILWAUKEE -- The Brewers placed reliever Brandon Kintzler on the 15-day disabled list late Friday with right triceps tendinitis and plucked yet another arm away from Triple-A Nashville.

The latest callup is right-hander Tim Dillard, whose contract was to be purchased by the Brewers prior to Saturday's game against the Pirates at Miller Park. Dillard, who made 15 appearances for Milwaukee in 2008-09, had a 3.51 ERA in 10 Triple-A relief appearances this season. Kintzler has not pitched since May 4, so the Brewers backdated his DL stint to May 5.

"Hopefully, it's not more than [another] week," Kintzler said.

Kintzler has been dealing with discomfort in his right triceps and forearm. He threw a bullpen session on Monday, underwent an MRI on Tuesday that showed no structural damage, then threw another bullpen on Wednesday.

Each time he threw, he had a setback.

"They say it starts with the triceps, but [the pain] shoots up my forearm," he said. "It's hard to explain. They think it's muscle fatigue.

"I have days where it feels better, then days where it doesn't feel good at all."

Asked whether the clean MRI gave him some peace of mind, Kintzler said, "An MRI doesn't always show everything."

The Brewers elected to call up Dillard over right-hander Sean Green, who started the year with the Brewers but was optioned down on May 5. He surrendered five earned runs on seven hits and two walks in his first four Triple-A innings.

Brewers cut ties with former prospect Periard

MILWAUKEE -- Onetime Brewers pitching prospect and 40-man roster member Alex Periard was released on Friday.

Periard will not turn 24 until June but already has a long medical history. He was limited to 12 games in 2009 because of shoulder stiffness, then pitched in only 15 games last season while dealing with vertigo.

He was struggling to get through innings at extended spring camp, Brewers farm director Reid Nichols said.

"His velocity and command did not come back," Nichols wrote in an e-mail. "Arm health was fine, [he] just lost the ability to compete."

Periard was the Brewers' 16th round Draft pick in 2004. The team on Friday also released 2009 25th-round pick Demetrius McKelvie, an outfielder who batted .192 in parts of two seasons.

Last call

Brewers left fielder Ryan Braun had a hit and three RBIs on Friday after exiting Wednesday afternoon with a bruised left ankle. He's started all 38 games this season.
