Key hole in third round of the Masters

A look at the key hole in Saturday's third round of the Masters:

HOLE: No. 13

YARDAGE: 510

PAR: 5

STROKE AVERAGE: 4.58

RANK: 18th

KEY FACT: Rory McIlroy and Jason Day were tied at 9 under when they got to the 13th, the easiest hole on the course. Day knocked his second shot over the green and flubbed a chip, the ball rolling back to his feet. He wound up making bogey, which became a two-shot swing when McIlroy rolled in a birdie.
