Brooks Koepka, who has won two of the last three majors, held a share of the first-round Masters lead with Bryson DeChambeau while three-time champion Phil Mickelson was one shot off the pace on Thursday.
Koepka, who missed last year's Masters with a wrist injury, used a combination of jaw-dropping power and laser-like irons to card a six-under-par 66 to sit atop the leaderboard with Bryson DeChambeau, who came within inches of a closing eagle.
American Koepka, who does not have a top-10 finish in three starts at the Masters, enjoyed a four-hole birdie run from the 12th to pull ahead but had to settle for a share of the lead after DeChambeau closed with four consecutive birdies.
DeChambeau, who was playing two groups ahead of Koepka and nearly aced the par-three 16th, almost walked into the clubhouse with the outright lead but his approach at the 18th rammed into the flagstick and settled inches away for a tap-in birdie.

This time last year Reed won his first major by finishing one shot clear of Rickie Fowler and earning the famous green jacket in the process.
"It’s been amazing having the jacket around,” Reed said: “Travelling with it and allowing other people to see it was definitely a treat.

McIlroy, playing alongside Rickie Fowler and Cameron Smith in the opening two rounds, is seeking to complete the career grand slam.
But can Rory overcome the mental scars of Masters past and claim the Green Jacket for himself?



In 1935, the hole featured a left fairway bunker that was later removed. A greenside bunker, front and left, was added in 1951.

Originally, the green was guarded by a lone bunker on the right. That bunker was reduced in size in 1966, and a left bunker was added in 1946.'
