Class-A Delmarva infielder Nicky Delmonico, one of the top prospects in the Orioles farm system, went on the disabled list for a knee injury Thursday, but the organization is optimistic the injury isn't serious.
Delmonico came out of Tuesday's game after a baserunner slid into him at second base trying to break up a double play. He had an MRI on Wednesday, but it hasn't been read. The Orioles believe Delmonico suffered a sprain at the worst and wanted to to an MRI as a precaution. The minor leagues have a seven-day DL.
