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.

Hideki Matsuyama now has a three-shot lead.
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).
