"The Nationals placed Ivan Rodriguez on the 15-day disabled list today, meaning their veteran catcher will miss the entirety of their 10-game road trip -- and will not be behind the plate on June 4, the likely first start of phenom Stephen Strasburg.

Rodriguez left Saturday's game against the Baltimore Orioles because of lower back pain after swinging and missing a pitch. He grimaced in the batter's box and received a visit from Nationals medical staff. He finished the at-bat and slammed his helmet to the ground. Rodriguez did not come back into the game to play defense, then sat out yesterday."
