Augusta, Georgia: LIV Golf's Brooks Koepka used a closing birdie to move into a three-way share of the Masters clubhouse lead with Jon Rahm and Viktor Hovland on Thursday while defending champion Scottie Scheffler lurked three shots back.

Koepka, one of 17 LIV Golf players left in the field after Kevin Na withdrew midway through his round, shot a sparkling seven-under-par 65 in ideal scoring conditions at humid Augusta National to join Spaniard Rahm and Norway's Hovland in the lead.

It's full focus

"There's only really a couple things I care about, is going to work out and going to play golf and that's it when we're here, and nothing else really matters," Koepka told reporters. "It's full focus on this and trying to walk out of here with a Green Jacket."

The only blemish on the scorecard for the four-time major champion, who won last week's LIV Golf event in Orlando, came at the par-five 13th hole where he carded a bogey after an errant tee shot forced him to take an unplayable lie.

But Koepka, finally looking comfortable after a knee injury that took a toll on his body, responded with birdies at the 15th and 17th before draining an eight-foot birdie putt at the last.

Hovland picked up another birdie at the new-look par-five 13th, and then capped his day with a string of pars for his first sub-70 round at Augusta National.

You have to have a short game

"I don't care how good you hit it out here, you have to chip the ball. You have to have a short game," said Hovland.

"Especially on that back nine when I hit a lot of bad shots, to be honest, but I managed to keep myself in it by hitting some really nice chips and making some really nice putts."

Rahm overcame his shaky start with a pair of birdies on the second and third holes and never looked back.

The Spaniard charged up the leaderboard when he followed a birdie at the seventh with an eagle at the eighth where he stuffed his approach shot to four feet before capping his round with the fourth of his back-nine birdies.

Woods, who has never missed a cut at Augusta National as a professional, has played one event this year and it showed as he rarely gave himself any opportunities and admitted to feeling sore after a 74 that was his worst Masters start since 2004.

"Got a lot of good looks and I thought I was hitting a lot of good putts, just hitting a lot of edges, which happens," said Scheffler. "These greens are not easy to putt and you can't expect to make everything."

Rory McIlroy, who is making his ninth attempt at completing the career Grand Slam, opened with a 72.
