I don't think we can blame Mark McQwire for bringing his own balls to the baseball games. "Throw me this ball and you can be part of history"
I would love to see the golf balls used in the Masters checked. Make it compulsory for ALL players to turn in the ball USED on certain holes. There are ProVs and there are ProVs, do we think the Nike we buy is the same as the one used by some Tour players? I remember Moe Norman checking some balls (Tour Edition used by 2 players, one had just shot 62) at the Canadian Open, Moe used to carry a ring in his pocket to check balls.
"Never touches the ring, never touches the ring! too small!"
The Ryder Cup Committee should also come up with a ball for the competion, solve the problem of deciding whose custom ball they use in foursome play.
