Barger turns down Big Papi's 'My Dawg' shirt: 'It's awesome, but no'

Addison Barger isn't going to accept a free shirt from just anyone.

Especially not one with direct ties to an AL East rival.

The Toronto Blue Jays slugger became the first player in MLB history to hit a pinch-hit grand slam in Game 1 of the World Series on Friday, and was rewarded with one of the most prestigious postseason mementoes ever handed out: a David Ortiz "My Dawg" T-shirt.

Despite the gesture from the Hall of Famer and Boston Red Sox legend, Barger just couldn't accept it.

"No, I left it. It has Red Sox on it, I'm not wearing that. Are you kidding me?" Barger joked postgame. "I'm not wearing a (team's shirt) that's in our division. No way. It's awesome, but no."

Some rivalries are bigger than others.
