Roy Halladay Poses Behind Unaware Fan In Roy Halladay Jersey

A fan in a Roy Halladay jersey had the chance meeting of a lifetime. Too bad he didn't know it.

The actual Roy Halladay, the retired ace pitcher, spotted the fan and secretly took a picture with him.

Halladay's former Toronto Blue Jays teammate, Luis Lopez, approved of the stunt.

That fan must be kicking himself right now.
