SCOTTSDALE, Ariz. -- The Brewers traded Minor League reliever Darren Byrd to the A's on Wednesday for third baseman Stephen Parker, a 25-year-old left-handed hitter who will head to Triple-A Nashville.
Parker was Oakland's fifth-round Draft pick in 2009 out of BYU, and has batted .277 with 43 home runs and 262 RBIs in four professional seasons. His best year was 2010 in the hitter-friendly Class A California League, where Parker hit .296 with 21 home runs and 98 RBIs.
Last season, Parker batted .256 with seven home runs and 47 RBIs in 99 games with Triple-A Sacramento. The Brewers had an opening at Nashville after veteran infielder Bobby Crosby elected free agency on Monday.
Byrd, 26, is a right-hander who has pitched exclusively in relief at Double-A Huntsville in the past two seasons. He briefly pitched in Milwaukee's big league camp before the team returned him to the Minors on March 7.
