This is a bold move for a Red Sox fan!

Ben Affleck made a surprise appearance at the ESPYs to present retired Yankee superstar Derek Jeter with the Icon award on Wednesday night, and his classy introduction made us love the actor even more than we already do!

"There was something about him that made the boos ring a little hollow. Maybe it was imitable class. Maybe it was that he won with dignity and lost with grace. Maybe it was simply that we knew no matter what, he was a winner regardless. Boston sports fans can be many things, but we know baseball, and we respect those who play the game the way it was meant to be played," he began.

The Batman star continued to sing the baseball player's praises, and thank him for all he did for the sport.

"He broke my heart 100 times, if not more. And he broke it again when he retired, because he was absolutely one of the very best ever to play the game of baseball. So to you, Derek Jeter, I tip my hat and I thank you for every last moment of your incredible career. You made the game better for everyone," he gushed.

This is the Oscar winner's second public appearance since he announced his split with wife Jennifer Garner. The Boston hunk appeared at Comic-Con last weekend.

We wonder how bean town feels about their golden boy gushing over a rival?!
