All 30 players left in can still mathematically win the FedEx Cup but the top-five will be guaranteed victory by winning next week's Tour Championship. Paul Krishnamurty outlines precisely what they have to do...
"A top-three finish would make Rose hard to beat. Not too much of an ask, considering recent form and his last five East Lake results of 10/2/4/6/2."
Back Justin Rose @ [3.85]
Numerous paths for leader Bryson Dechambeau
The latest superstar to emerge off the American conveyer belt leads going into the FedEx decider having landed back-to-back victories in the first two play-offs. Vijay Singh took an identical route to the FedEx title back in 2008 and a further positive is that the last two champions at TPC Boston went on to claim the main prize. One negative, though, is that Bryson will be making his East Lake debut.
Scenarios: Pole position is a huge advantage for Dechambeau, offering numerous paths to the FedEx top prize. Like all the top-five, victory at East Lake will assure him of victory and he'd retain a mathematical chance if finishing in the top-29 (out of 30!). Merely a top-six finish will put him right in the mix.
Justin Rose the rightful favourite
The new world number one is now the FedEx favourite and rightly so. Four wins and three second places over the past year confirm he's better than ever, and relentlessly consistent. Although failing to convert so far in this year's play-offs, he was runner-up in the last two and three times in his last five events.
Scenarios: Likewise Justin has a few paths and as low as ninth place could be enough. More realistically, a top-three finish would make him hard to beat. Not too much of an ask, considering recent form and his last five East Lake results of 10/2/4/6/2.
Tony Finau rewarded for consistency
This could be quite a story. Finau hasn't won this season, and has only once prevailed on the PGA Tour, in the much lower grade Puerto Rico Open. Nevertheless he heads to East Lake in third place and just earned the final wildcard pick for the Ryder Cup. Few will argue with that after a very consistent season and he's held his form well during the play-offs, finishing 2/4/8. Tony fared promisingly in seventh on last year's East Lake debut, saving his best round for last.
Scenarios: Finau's alternative routes to the title require at worst, a two-way tie for third. Second including ties could well be enough.
Dustin Johnson needs a PB at East Lake
Dustin is still searching for his first FedEx title and, if an extra incentive were needed, he must be determined to reclaim the world number one spot from Rose at the earliest opportunity. Form has fallen back since a mid-summer peak, however, and he failed to contend in any of the first three play-offs.
Scenarios: Winning the Tour Championship would hand Dustin the title, but he cannot afford anything worse than a three-way tie for second place. That will require a personal best at East Lake, where's he's never bettered fifth place in eight attempts.
Justin Thomas in with a shout
The defending FedEx champion remains in control of his own fate having sneaked into fifth place. The play-offs weren't especially rewarding - producing finishes of 8/24/12 and not always convincing with his irons - but only last month Thomas won his seventh title since the start of 2017 at the WGC-Bridgestone.
Scenarios: In order to defend his title, JT will have to win the Tour Championship or finish, at worst, in a two-way tie for second. Well within range, considering he was second last year and sixth on debut in 2016.
