yep.... from Rotoworld:
John Patterson - S - Nationals
Nationals placed RHP John Patterson on the 15-day disabled list, retroactive to April 23, with a strained flexor muscle in his right forearm.
Instead of sending down Mike O'Connor, Patterson is placed on the Dl toopen up a spot for Zach Day. It seems like the Nationals have been underestimating Patterson's problem right from the start, so there's very good reason for concern now. O'Connor will likely get another start in his place on Wednesday. The Nationals also need a starter for Sunday, but they may go with a bullpen day. Apr. 28 - 5:53 pm et
My NL only team is sinking fast..... Beltran, Lee, Patterson, Hermida... ugh.
