Brewers trade reliever Francisco Rodriguez to Orioles
Rodriguez has appeared in 25 games for the Brewers this season and has a 1-1 record with a 1.09 ERA and 10 saves. In his 11-year career, he has a 2.64 ERA with 304 saves.
Delmonico, 20, was a sixth-round pick in 2011 and is hitting .244 in High-A Frederick this season.
The Brewers are currently 19 games behind the St. Louis Cardinals in the National League Central and have very little chance of making the postseason.
