Hideki Matsuyama, Kevin Chappell and Dustin Johnson lead the Tour Championship on -4 after the first round.

The trio lead by a shot from a further group of three including Jason Day. Rory McIlroy remains in contention to win the tournament, and the FedEx up on -2.

Johnson, who went into the tournament, at the top of the FedEx Cup rankings remains on course to win the $10million jackpot. The winner of the tournament wins a paltry-in-comparison $1.53million.

Johnson, Patrick Reed, Adam Scott, Day and Paul Casey are all guaranteed the FedEx Cup title if the win the tournament. Reed is the only player of the group currently over par.

The tournament has the added incentive of a potential Ryder Cup wildcard pick for an American player ahead of next week's event. Chappell is currently the top-ranked American not in the team, closely followed by Kevin Kisner (-3) and Justin Thomas (-2).

If McIlroy is to win the FedEx Cup for the first time, he will have to win the tournament, and hope that Dustin Johnson finished tied-second or worst. If Johnson were to finish alone in second place, he would with the $10million bonus.
