Dustin Johnson and Rickie Fowler moved into an early share of the lead during the second round at The Northern Trust.
The American pair moved to six-under-par following their second rounds with three-time PGA Tour winner Jhonattan Vegas also finishing at the same mark at Glen Oaks Club.
Johnson, who opened with a five-under 65, carded a one-under 69 in his second round which saw the world No 1 mix three birdies with two bogeys.
The 2016 US Open winner missed out on winning the FedEx Cup last year after a disappointing final round three-over 73 at the Tour Championship which was eventually won by Rory McIlroy after a lengthy three-way playoff.
World No 10 Fowler, who has one victory on the PGA Tour this year at The Honda Classic, mixed five birdies with a solitary bogey for a four-under 66 to move into early contention.
Meanwhile Vegas, who won the Canadian Open last month, carded a blemish-free five-under 65 to join the American Ryder Cup pair.
Jon Rahm, who came into the week in sixth position in the FedEx standings, posted a second successive round of 68 to finish a four-under par and the Spaniard is well placed to make a move over the weekend.
Paul Casey was another one of the prominent morning starters in the second round and the Englishman, who has enjoyed a consistent season on the PGA Tour, finished the day at three-under after a second round two-under 68 which is where Patrick Reed also finds himself after a three-under 67.
The Northern Trust is the first event of the four-tournament series of play-off events and features the top 125 on the FedEx Cup list, with the number cut to 100 ahead of the Dell Technologies Championship in Boston.
