BILLY HORSCHEL IS THE HOT PLAYER on the PGA Tour at the moment. The winner of last week's BMW Championship, Horschel has charged ahead at East Lake Golf Club, where he holds the halfway lead at the season-ending TOUR Championship.
Horschel has posted a pair of 66s to stand at 8 under par, two shots ahead of Rory McIlroy, Chris Kirk and Jason Day.
Golf Digest published a swing sequence of Horschel in October 2013. "Mr. Intensity: Billy Horschel's aggressive action has led to a breakout year," wrote the magazine.
There are two dozen images of Horschel's swing, starting here.
