It's safe to say Rory McIlroy has some good memories from New Haven, Conn.

The world's top-ranked golfer was back in Connecticut this weekend to accompany his girlfriend, Caroline Wozniacki, who is competing in this week's New Haven Open. And while McIlroy was there, he figured he might as well test his luck again.

The PGA Championship winner took to the field at the Yale Bowl for a special challenge. McIlroy attempted to whack a tennis ball into one of the stadium's famed tunnels. Unfortunately for McIlroy, and pyromaniacs everywhere, his suggestion of using a flaming tennis ball was denied.

This is probably McIlroy's second best trick shot. He did, after all, nail a cross bar with a golf ball.
