The Milwaukee Brewers have placed pitcher Shaun Marcum on the 15-day disabled list because of tightness in his right elbow.

Marcum was scratched from his scheduled start last Tuesday because of the injury and hasn't pitched since June 14. He is eligible to return June 30.

The 30-year-old right-hander is 5-3 with a 3.39 earned run average in 13 starts this season, his second with the Brewers. He was 13-7 with a 3.54 ERA in 33 starts last year after being acquired from Toronto.

Marcum missed a good portion of the 2008 season with elbow problems and eventually underwent Tommy John surgery later that year before missing all of the 2009 campaign.

The Brewers activated first baseman Travis Ishikawa off the 15-day disabled list. Ishikawa had been sidelined since May 27 with a left oblique strain. He entered Saturday's action batting .250 in 32 games with four homers and 14 runs batted in.
