COURSE: Merion Golf Club
RESULT: Tied for second, two shots behind Justin Rose.
KEY MOMENT: Mickelson was one shot behind when he hit wedge over the green on the par-3 13th hole and made bogey. Still one shot behind in the 15th fairway, his wedge was so short that he used a wedge to chip from the putting green and made another bogey.
NOTEWORTHY: It was the first time Mickelson had the outright lead (one shot) going into the final round of a U.S. Open.
