The Nationals moved Stephen Strasburg back to the disabled list. He strained his left oblique. No word yet on the seriousness of the injury. Oblique strains can sideline a player a long time, but because the Nationals got Strasburg out of the game immediately, despite him wanting to pitch, this may not be too long. On top of that, he won’t miss that many games due to the four days off for the All-Star break.
