During the 1997 Verizon Heritage, Austin intentionally struck his head with his putter five times. He hit his head so hard that the shaft bent.
After the second round of the 2007 PGA Championship, Austin joked that he was named after actor Woody Harrelson (Harrelson being only three years older than Austin). He went on to finish 2nd behind Tiger Woods, his best major finish. This achievement moved Austin into the top 50 of the Official World Golf Rankings. During the 2007 Presidents Cup, Austin fell into a pond while attempting to hit a shot with one foot in the water. During his singles match against 2007 U.S. Open Champion Ángel Cabrera, he wore a pair of swimming goggles.
After struggling for years to maintain his PGA Tour Status, Austin won the 2013 Sanderson Farms Championship, his first PGA Tour win in six years. In that season's PGA Championship, Austin was given a four-stroke penalty for having fifteen clubs in his bag; he would miss the cut by one stroke. Although Austin didn't do well enough to earn entry into the FedEx Cup (137th after making two cuts in eight events, plus the win was an alternate event only worth 300 FedEx Cup points rather than 500), his win earned him a tour card through 2015. Despite his exemption, Austin decided to focus on the Champions Tour.
Austin was inducted into the University of Miami Sports Hall of Fame at its 40th Annual Banquet held February 13, 2008 at Miami's Jungle Island. He resides in Derby, Kansas.
