Strasburg was placed on the 15-day DL on Monday due to right elbow soreness.
Strasburg has been shelled for 15 earned runs over his last two starts, most recently allowing nine runs on nine hits across just 1.2 innings Wednesday in Colorado. While the Nationals initially dispelled any rumors of Strasburg dealing with a health issue, Monday's move would seem to contradict that, though at this point it's unclear if he's battling anything beyond general soreness. Strasburg was initially slated to take the hill Monday, but the Nationals will now recall A.J. Cole from Triple-A to start against the Orioles.
