Equipped To Lose

As I was flicking around the TV this weekend, I saw a few minutes of a golf tournament where a couple dozen golfers plunked their shots into the water while trying to get onto an island green. While it all seemed very miniature-golf-like to me, I couldn't help but wonder...is golf the only sport where the participants can lose their own equipment?

Major league baseball and NHL players don't have to provide the balls and pucks that may go over the wall or glass. The NFL puts up those nets to keep the pigskin from flying into the stands during field goal attempts. The NBA doesn't let fans keep the ball even if it does go into the crowd. I've never seen a tennis player lose his tennis racket to a sea of fans.

Can you think of one?
