Y.E. Yang (right) and Rory McIlroy, who face off in the same group at the third round of the 111th U.S. Open, inspect the putt line in a similar posture on the 15th hole (par 4). Both birdied the hole. McIlroy is atop the leaderboard and leads second-place Yang by eight strokes, and has taken a step closer to winning his first major PGA title.
