Brewers ace Ben Sheets was placed on the 15-day Disabled List on Monday with a finger injury. Sheets was hurt in Saturday's win over Colorado. He had an MRI on Monday and will be re-examined today to find out if he'll miss two weeks or a longer time. Sheets could be down 6-plus weeks depending on the results of tests today. With Sheets hurt and reliever Greg Spurling taking a leave from the team to deal with a family issue, GM Doug Melvin called up pitchers Manny Para and Grant Balfour from Triple-A Nashville.
