MILWAUKEE -- Robin Yount, still troubled by a shoulder injury that forced the All-Star shortstop to the outfield, will undergo another operation in the first week of September, the Milwaukee Brewers said Tuesday.
Yount underwent surgery during the off-season, but a team doctor said calcium deposits had built up since that operation.
Yount said last week his shoulder hurts as much as it did last year when he was relegated to the role of designated hitter at the end of the season.
He began this season in left field -- where there is less strain on a player's arm -- and recently was shifted to center. He also has been a designated hitter this year.
Yount, 29, was the Most Valuable Player in the American League in 1982. He entered Tuesday night's game with Detroit batting .283 with 12 homers and 56 RBI this year.
In another announcement, the Brewers recalled left-handed reliever Ray Searage and designated hitter-first baseman Carlos Ponce from Vancouver of the Pacific Coast League.
Searage, who began the season with the Brewers, was 2-0 with seven saves in 23 games with Vancouver. Ponce played in 107 games for the Whitecaps, batting .322 with 10 homers and 78 RBI.
Also, Milwaukee said pitcher Chuck Porter has been taken off the disabled list and sent to Beloit in the Midwest League for 20 days of rehabilitation.
