ST. LOUIS -- The Brewers, in need of fresh arms in their bullpen, made several roster moves following Saturday's game.
Milwaukee optioned right-hander Mike McClendon to Triple-A Nashville and on Sunday will transfer left-hander Chris Narveson to the 60-day disabled list and purchase the contract of right-hander Vinnie Chulk from Nashville.
Manager Ron Roenicke said the Brewers needed a fresh arm.
"Mac did a nice job giving us innings, but he's thrown 80-some pitches in three days," he said. "We weren't going to pitch him today. We weren't going to pitch him tomorrow. To cover us a little better we felt like we needed to get another arm in."
McClendon, 27, had a 10.13 ERA in 5 1/3 innings over three games. He had allowed six runs -- all earned -- on 10 hits while walking four and striking out three.
The 33-year-old Chulk last pitched in the Major Leagues with Cleveland in 2009, when he was 0-1 with a 3.75 ERA in 12 innings over eight games. He is 7-15 with a 4.33 ERA in 252 games over seven seasons.
Chulk appeared in seven games for Triple-A Nashville. He had a 3.18 ERA over 11 1/3 innings, with four runs (all earned) allowed on eight hits. He struck out 10 and walked five.
"He's got a good fastball," Roenicke said. "Sometimes in spring, what we saw, he gets a little out of his command, but he's got a nice fastball. He's got some experience. That helps."
Narveson, who is out for the season with a left rotator cuff injury, will have surgery on Tuesday in Milwaukee.
