Masters leaderboard 2017: Phil Mickelson bags a quick eagle on quest to become oldest Masters champ

Phil Mickelson got off to a quick start in his quest to win a fourth Masters tournament as the 46-year-old five-time major champion posted an eagle-3 on the second hole at Augusta National. Apparently, the pin placement was gettable, as two-time major winner Martin Kaymer also made eagle, holing out from 43 yards.

With the morning wave under way on a chilly and windy Augusta morning, Mickelson birdied No. 4 to get to 3-under and move into a tie with Thomas Pieters, who rang up three birdies in his first six holes. Should Lefty prevail on Sunday night, he would overtake Jack Nicklaus as the oldest player to win a green jacket.

With Dustin Johnson “cautiously optimistic” to play after hurting his back with a fall down some stairs at his rental house in Augusta, according to Golf Channel’s Todd Lewis, it will be interesting to see if the reigning U.S. Open champion can go full out. Physiotherapist Dr. Ara Suppiah, who is treating DJ, has suggested that his patient not go at it 100 percent, but rather swing clubs at more like 75 percent.

Daniel Summerhays had an eventful morning, nearly drilling an ace on Jordan Spieth’s favorite hole, the short but treacherous par-3 12th. A tap-in followed for Summerhays, who was at even-par 72 through 15 holes.
