Tiger Woods Auctions Back Up Putter

Tiger Woods made a nice penny after placing a back up putter up for auction.

He sold his 2000 back up putter for auction and brought in a whopping $89,000.

The putter was given to him by Scotty Cameron who usually provides Woods with his putters.

Cameron validates his putters by providing a certificate of authenticity, and is engraved with Woods's name on its backside, as well as T.W. on the front toe—is "made for Tiger Woods."

Woods's 2000 PGA Tour campaign remains among the most dominant of his career.

The putter sold for double what the cost, which has us wondering. What will Tiger do with the cash?
