Final round

Sunday, August 1, 2010

Fred Couples birdied the par-4 1st hole to take a one stroke lead over Bernhard Langer. On the par-5 2nd hole, Couples drove his tee shot into the first cut of rough and was left with 227-yards for his second shot. He decided to lay up short of a water hazard which surrounds the front of the second green and was left with 69-yards for his third shot. Couples' third shot found the water and resulted in a triple bogey. Langer made a long birdie putt on the 2nd green to take a three shot lead over Couples. He extended his lead to four strokes with a birdie on the par-4 6th hole. After two late birdies by Couples, Langer entered the 72nd hole with a two stroke lead and converted a 7-foot par putt to win his second consecutive senior major championship by three strokes.
