Hideki Matsuyama produced a flawless seven-under-par 65 as his stunning late blitz earned a four-stroke lead heading into the final round of The Masters.

Matsuyama – chasing his maiden major title and Japan's first in men's golf – made a huge splash on moving day at Augusta, where the 29-year-old seized control following a weather delay on Saturday.

After inclement weather halted proceedings, Matsuyama jumped out of the blocks and gained six shots in seven holes to leave overnight leader Justin Rose in his tracks.

Matsuyama – who birdied the seventh hole on a bogey-free front nine – was red hot following the turn, the five-time PGA Tour champion birdieing the 11th and 12th.

Unstoppable, Matsuyama eagled the 15th before following that up with back-to-back birdies at the 16th and 17th as he soared to 11 under through 54 holes.

Matsuyama – making his 87th start since his last victory at the 2017 WGC-FedEx St Jude Invitational – posted the first bogey-free round this week and his best score in 37 rounds at The Masters.

Xander Schauffele and Marc Leishman also made their moves to join Rose and Will Zalatoris in a share of second spot heading into Sunday's final round.

Runner-up in 2019, American Schauffele improved 10 positions thanks to a third-round 68, which included an eagle, four birdies and two bogeys.

Leishman (70) – who finished tied for fourth in 2013 – enjoyed a strong finish, with two birdies from his final bogey-free six holes leaving him in a mix to become just the second Australian to win a green jacket after Adam Scott (2013).

The penultimate day did not go according to plan for Englishman Rose, who signed for a second consecutive 72 in Georgia.

It was a mixed day for Rose as the one-time major champion split three birdies and as many bogeys, while American Zalatoris (71) is also seven under overall.

Highlighted by an ace on the sixth hole, Corey Conners posted a four-under-par 68 to be outright sixth, five strokes behind Matsuyama.

Former world number one and 2015 champion Jordan Spieth – who ended his near-four-year title drought last week – will begin Sunday six shots off the pace following his 72.

Another former Masters winner, 2018 champion Patrick Reed, is four strokes further back after shooting a two-under-par 70 to be level alongside Justin Thomas (75) and last year's runner-up Cameron Smith (73).

Defending champion Dustin Johnson failed to hit the ground running in testing conditions when he started the defence of his Masters title on Thursday.

Johnson donned the green jacket for the first time last November, finishing the tournament on a record-breaking 20 under par.

The world number one made only four bogeys as he blew the field away in the 2020 major at Augusta, but he dropped two shots in his opening five holes five months later, with patrons returning under blue skies.

Birdies were at a premium when the tournament got under way on much quicker, firmer greens than those seen in last year's tournament.

Two-time major champion Johnson started by dropping a shot after running through the first green with his second shot. Although he hit straight back with a birdie at the par-five second, Johnson was back at one over after failing to sink a par putt at the fifth.

Hideki Matsuyama led the way on three under through eight holes after draining an eagle putt at the eighth, with Christiaan Bezuidenhout and Si Woo Kim just a shot behind.

New father Jon Rahm, Patrick Reed and Paul Casey were among a host of players on one under following early birdies.

The recently in-form Lee Westwood was struggling on three over through six after a double bogey at the third, while Rory McIlroy dropped to one over with a dropped shot at the fifth and Brooks Koepka was level par eight holes into his first round.

Collin Morikawa added the WGC-Workday Championship to his growing list of achievements after triumphing by three strokes.

Winner of last year's U.S. PGA Championship, Morikawa used a three-under-par 69 to seal victory at the star-studded World Golf Championships event in Florida ahead of Viktor Hovland, Brooks Koepka and Billy Horschel on Sunday.

Morikawa holed four birdies and just one bogey to finish 18 under for his fourth PGA Tour crown – the most by any player currently aged under 25.

He also joins Tiger Woods as the only player to win a major championship and WGC event before turning 25.

Further to that feat, Morikawa is the seventh player to claim four or more PGA Tour tournaments – including a major – under the age of 25, following in the footsteps of Woods, Jack Nicklaus, Jordan Spieth, Rory McIlroy, Justin Thomas and Jerry Pate.

The overnight leader by two strokes, Morikawa recovered from a slow start after bogeying his second hole of the final round – the 24-year-old American birdieing three of five holes before the turn as he ended the day without dropping another shot.

Norwegian star Hovland mounted a serious title charge following a five-under par 67, but he was unable to stop Morikawa.

Hovland finished tied for second alongside four-time major champion Koepka (70) and Horschel (70) at The Concession Golf Club.

McIlroy's final-round 71 saw the former world number one and four-time major winner slip down into a tie for sixth, six strokes adrift of Morikawa.

Defending champion Patrick Reed (72) ended the co-sanctioned PGA and European Tour tournament a shot further back.

Justin Thomas (71) earned a share of 15th at eight under, a stroke better off than U.S. Open champion Bryson DeChambeau (69).

It was a forgettable finish for world number one Dustin Johnson, who closed proceedings with a six-over-par 78.

The two-time tournament winner plummeted 12 positions to T54 at five over the card.
