MILWAUKEE -- In need of a fresh arm in the bullpen and desiring a more effective one, the Brewers shipped out right-handed reliever Vinnie Chulk on Saturday and brought in Juan Perez, a left-hander who impressed in Spring Training before he was beset by injuries.
Perez's bid for an Opening Day roster spot was derailed when he suffered a partially collapsed left lung on March 11. Later, he missed the start of Triple-A Nashville's season with a stiff back.
But Perez has since pitched well, charged with only one earned run in 10 2/3 innings at Triple-A, with 15 strikeouts.
Perez throws a power fastball and slider, and is "a true left-hander to get out lefties," manager Ron Roenicke said.
"Manny [Parra] has been doing a good job getting out the left-handers, but he can go through righties, he can be a long man. [Perez] gives us a guy maybe more specific to what we need. We've come across a lot of left-handed lineups, and we're getting stuck in that middle relief part where we're having to put in some right-handers against some lefties. We'd rather not do that."
Chulk was designated for assignment after allowing 10 runs and 17 hits in nine innings of relief. He had pitched three straight days and would have been unavailable on Saturday.
Chulk has the right to refuse an outright assignment to Nashville. Assistant general manager Gord Ash urged Chulk to accept.
"As I reminded him, he came out of nowhere and made an impression," Ash said. "He has to take solace in that, and it can happen again. The way we're going, 30 days from now, we could use him again."
