With the Irishman 2 up playing the 17th, Mahan was under serious pressure to pull something out the bag. After coming up short on the 196-yard par 3, and with his opponent in the fringe 35 feet away, the world number 14 flubbed his chip, advancing the ball only a few yards to all but hand team Europe victory. Fast forward to 31.15 in the video below to relive the shot.

How bad was that chip? Let's find out using Shot Quality. A Shot Quality of 0 represents the worst possible outcome, such as OOB or lost ball; 100 represents the standard expected of an average male tour player; 200 denotes statistical perfection, such as a hole in one or holing out from long distance.
