Watch: Harper initiates hat trade with Phillies fans

Reigning NL MVP Bryce Harper and a few fans at Citizens Bank Park made a rare deal during a game between the Philadelphia Phillies and San Diego Padres on Thursday.

Harper wanted a hat from the spectators and decided to give his cap, which he signed, in return:

"Just really liked the hat, so I signed mine and asked if he wanted to trade," Harper said, according to Todd Zolecki of MLB.com. "He was really cool about it and made it happen. Always fun interacting with the fans here at home."

"He was like, 'Yo, bro, can I swap hats with your boy,'" 21-year-old Gavin McHugh said, according to Dan Gelston of The Associated Press. "Hopefully we can get connected down the road."
