It's a fact, Bryce Harper's presence in the Nationals' lineup is affecting all aspects of the team.

According to a report in The Washington Post, utility man Mark DeRosa's slowed progress in returning to action from the disabled list is the product of an overly exuberant high-five with Harper.

DeRosa said he aggravated his strained left oblique muscle congratulating the young Nats star after Harper stole home against the Phillies Sunday night.

I dont know if that set back the rehab or not, said Manager Davey Johnson. But I said, Why didnt use your right hand? He said it was spur of the moment.
