Rory McIlroy charged into contention at the Deutsche Bank Championship in Boston on Sunday as he fired a third-round 64.
McIlroy's round moved him to 10 under par and left him two shots behind leader Russell Henley of the United States, who shot 65.
The Northern Irishman is tied third with American Chris Kirk, who also hit a 64, and Australia's Jason Day (69).
McIlroy, 25, is second in the FedEx Cup standings behind Hunter Mahan.
The in-form world number one managed seven birdies in his penultimate round after making a fast start.
McIlroy birdied the second and third before picking up another shot at the seventh after a 132-yard approach to nine feet.

Two more excellent up and downs at the 13th and 15th left him with birdies and he was close to holing his nine-iron tee shot at the 16th as he moved further up the leaderboard.
"It was just another solid day's golf and obviously sets me up nicely for tomorrow," said McIlroy after his round.
"Most of the back nine, I didn't need to hole anything of significant length."
McIlroy has won three of his last four tournaments heading into Boston, having triumphed at the Open Championship, the WGC-Bridgestone Invitational and the US PGA Championship in recent weeks.
England's Ian Poulter was unable to mount a third-day charge as a level-par 71 kept him on two under.
Poulter is expected to earn a wildcard from European Ryder Cup captain Paul McGinley on Tuesday thanks to his previous success in the competition.
Fellow Englishman Luke Donald, who is also hoping to earn one of the three wildcards on offer, could only manage a 74 on Sunday, which left him sharing 67th place on four over.
Henley tops the standings following a six-under round that contained seven birdies and just a solitary blemish at the par-four sixth.
Billy Horschel is one shot adrift of his United States compatriot after finishing his round with three successive birdies to card a 67.
