Henrik Stenson fired a stunning third round of 65 to claim the outright lead heading into the final round of the Deutsche Bank Championship.
The Swede carded four birdies and an eagle at TPC Boston on Sunday to move to 13-under for the tournament, which is the second of the four events that make up the FedEx Cup play-off series.
That total gives him a single-stroke advantage ahead of Rickie Fowler who signed for a 67, while Sean O’Hair and Matt Jones are a further shot back in a tie for third.
It was a bad day for overnight leader Charley Hoffman though, as a suspected back problem meant he could only manage a 76 to tumble down the leaderboard in Norton.
The Deutsche Bank is unique on the PGA Tour as it is the only event on the calendar to finish on a Monday due to the Labor Day celebrations.
Stenson won the tournament back in 2013 and is currently the 2.00 favourite to take the title ahead of Fowler (3.75) and Jones (11.00).
The 39-year-old arrived in Massachusetts after finishing second at last week’s Barclays and admits he is in the perfect position heading into the final round.
“It’s a good time to start playing well,” said Stenson. “It’s a big event and lots to play for.
“I’m happy with the progress I made and it gave me a little bit of a confidence boost last week that I had a nice tournament. I hope I can have another one here tomorrow.”
