Video below (via MLB.com) of Bryce Harper's ridiculous hustle double on a chop up the middle on Sunday in Baltimore. Oh, and here's Davey Johnson talking about Harper's back (still sore) and something about contraptions:
"I've seen him with all kinds of contraptions [on his back], but I think right now it's for prevention."
