MILWAUKEE -- Moments after their frustrating 6-5 loss to the Cincinnati Reds on Friday night at Miller Park, the Brewers made a pair of roster moves to open spots for two other players.

Optioned to Triple-A Nashville were infielder Irving Falu, who is hitless in 11 games since being called up on May 26, and reserve outfielder Logan Schafer, who has struggled offensively in limited action this season.

The move leaves Milwaukee without an extra outfielder, but utility man Elian Hererra will rejoin the Brewers on Saturday. He can play in both the infield and the outfield, making him a valuable commodity as the Brewers go with an extra pitcher.

That extra arm is left-hander Tom Gorzelanny, who will join the Brewers for the first time this season when he's activated from the disabled list Saturday.

Gorzelanny underwent surgery on his left shoulder last winter and got off to a slow start in spring training, delaying his return.

He finally began a minor league rehab assignment last month and posted a 1.15 ERA in 15 1/3 innings over 10 appearances for Class A Brevard County and Nashville.

"No complaints," manager Ron Roenicke said. "His velocity was up. ... He's been pitching well. The command has been good, the slider's good. Obviously, we're hoping to see that same thing."

Gorzelanny gives Roenicke four left-handers in the bullpen.

Schafer, 27, had a .190 average (15-for-79) in 37 games (20 starts). In 15 pinch-hit appearances, Schafer is 2-for-13 -- he picked up his second pinch-hit of the season Friday.

Roenicke said the decision to send Schafer to Nashville was made with the hope that he would get back into a groove.

"(Schafer) needs to go down and get some at-bats and get his swing back," Roenicke said. "He did a nice job today with the pinch-hit."
