Gorzelanny's pending activation sparks moves

MILWAUKEE -- Left-hander Tom Gorzelanny will be active in the Brewers' bullpen for the first time on Saturday as the result of a series of roster moves late Friday night.

Optioned to Triple-A Nashville were outfielder Logan Schafer and utility man Irving Falu, creating space for Gorzelanny to return from the disabled list and for another utility man, Elian Herrera, to come up from Nashville. With the bullpen now eight arms strong and the bench one man short, the Brewers valued Herrera's switch-hitting bat and greater defensive versatility.

Gorzelanny has been sidelined since having surgery to repair tears to the rotator cuff and labrum in his left shoulder in early December. He began a 30-day rehab assignment at Class A Brevard County on May 14 before moving up to Triple-A the following week.

Though manager Ron Roenicke had been concerned about Gorzelanny's velocity in recent weeks, he said reports from the last few appearances in Nashville were more encouraging.

"No complaints. Velocity was up two outings ago, it was up really well," Roenicke said. "The command has been good, the slider's good. Obviously, we're hoping to see the same thing."

Gorzelanny made 10 appearances in the Minors, accumulating a 1.15 ERA, 12 strikeouts and two walks over 15 2/3 innings.

His activation will make for four left-handed options in the bullpen. Roenicke would like to ease Gorzelanny in but knows that might not be an option during this weekend's series against the Reds.

"He'll be in there as needed," Roenicke said. "It's usually [Joey] Votto-[Brandon] Phillips-[Jay] Bruce [for Cincinnati], and with that combination there, that's a good time to put him in. When he's throwing right, like he was last year -- especially when we had him in relief last year -- he pitched against anybody. It didn't matter."

Gorzelanny had a 3.90 ERA in 43 appearances (10 starts) with Milwaukee last season. He struck out 83 and walked 31 in 85 1/3 innings.

The combination of roster moves meant a surprising demotion for Schafer, who has not played regularly in the Minors since 2012. Schafer delivered a pinch-hit single in Friday's 6-5 loss to the Reds but entered the day with a .179 batting average in irregular duty.

"We're going with one extra guy in the bullpen and a four-man bench, so we'll try this for a little bit," Roenicke said. "Schafer needs to go down and get some at-bats and get his swing back. That's our idea."

Thornburg, Henderson start throwing

MILWAUKEE -- Though the Brewers still aren't sure what's wrong with the right elbow of reliever Tyler Thornburg, they sent him to their Spring Training facility in Arizona to rehab and get into a throwing routine.

Thornburg was placed on the disabled list on June 7 with soreness in the elbow, and though the team has ruled out Tommy John surgery after an MRI showed a clean ulnar collateral ligament, they haven't announced a more specific diagnosis. Manager Ron Roenicke said last Tuesday that the team was holding off on an official diagnosis until Thornburg can see a radiologist on Tuesday or Wednesday.

"It's just soreness, something that runs down, kind of in the forearm," Roenicke said. "Because it had been there for a little bit, they're going to go easy with him. He's in Arizona. They won't play catch yet, but I think shortly he'll be playing catch again."

Roenicke said that Thornburg's stint could last longer than 15 games, though he is not anticipating that it would.

Thornburg will soon be joined by fellow reliever Jim Henderson, who has been on the DL since May 2 with inflammation in his right shoulder. Roenicke said that Henderson has been progressing and has played catch in Milwaukee, but that the training staff still hasn't given him a projected return date.

The Brewers head to Arizona on Monday for a four-game set with the D-backs, and will meet up with the two relievers there.

"It's just so they can get their routine there, because we're only [in Milwaukee] for three days and then go out again," Roenicke said.

Worth noting

• This weekend's series against the Reds is the only home series for the Brewers in a stretch in which they will play 15 of 18 games on the road. The Brewers went 5-3 on their first eight-game road trip, against the Twins, Pirates and Mets.

• The struggling Jean Segura got a day off on Friday, with Irving Falu starting at shortstop in his place.
