LAS VEGAS -- With American Pharoah winning horse racing's Triple Crown and Serena Williams marching toward a Grand Slam in women's tennis, it looked like this could be the year of the sweep when Jordan Spieth was attempting to force his way into the playoff at The Open in July. However, Spieth came up just short at St. Andrews -- and it was a great effort, as he missed the playoff by just one stroke.
So, the PGA Championship that starts Thursday at Whistling Straits maintains its status as the last major of the year, but without a historic Grand Slam on the line. Still, there are plenty of storylines and interest from bettors.
