Super Smith makes his move in New Jersey
Australia's Cameron Smith moved into a share of the lead with Jon Rahm at The Northern Trust after a sensational round of 60 on Saturday.
The world number 28 rose 24 places on the leaderboard, narrowly missing out on a magical round of 59 and he is now 2.20 to get his hands on the trophy, with the Spaniard 4001.00.
Smith put the pressure on at Liberty National after making 11 birdies and he now has a great chance of victory after Rahm's second consecutive round of 67.
Mixed back nine for Rahm
Rahm turned in 32 and reached 17-under par, but he double-bogeyed the 13th and dropped another shot on the 16th. Birdies on 15 and 17 got him back level and the duo will now fight it out at the top of the leaderboard, although play will not resume in New Jersey until Monday.
The opening event of the FedExCup playoffs will return a day later than planned, after warnings from the National Hurricane Center, with Tropical Storm Henri due in the area on Sunday.
South Africa's Erik van Rooyen is still in contention in third place on 15-under par, while American duo Justin Thomas and Tony Finau share fourth a shot further back.
Shane Lowry, Viktor Hovland and Tom Hoge are sixth and they will still fancy their chances on 13-under par.
Break could benefit Smith
Smith was the man under the spotlight after his impressive round and believes the extra day of rest may do him a world of good.
He told Sky Sports: "I always think it's hard to back up a really good round, so maybe the day off will help me out. I don't know what I'm going to do on Sunday; I've never been in this situation either!
"Probably just a little bit of a rest. A round like this usually takes it out of you a little bit, the adrenaline, the highs and the lows. Sleep in, maybe a little bit of gym and come out Monday firing."
