Ruoning Yin of China was victorious this past Sunday at Baltusrol Golf Club. Her win at the KPMG Women's PGA Championship was her first major and her second LPGA victory of the year.

Yin's final round 67, which included five birdies on the Lower Course, was enough to secure a one-shot win. What struck me the most about Yin’s win was the notion of “one shot” and how critical it is in golf — especially among the professional ranks. It was a one-shot win in this case, but during an entire tournament, one shot each day can mean a lot.
