Backup catcher Caleb Joseph went on the DL today with a testicular injury. Even though Matt Wieters has been mashing (batting .400 since May 10) and caught three days in a row last week for the first time since before Tommy John surgery, Buck Showalter said that Wieters' role won't expand. "Doesn't change anything about Matt," said the Orioles manager. "We're not going to start pushing up his load and jeopardize something down the road." Catcher Franscico Pena, called up today, will assume Joseph's role.
