Marc Leishman is off to a strong start -- again.

1. Jordan Spieth, United States -- Even though he had his chances to win the first two playoff events before finishing second to Dustin Johnson in The Northern Trust and to Justin Thomas in the Dell Technologies Championship, Spieth leads the FedExCup standings heading to the third playoff event. He is guaranteed to be in the top five next week at the Tour Championship at East Lake in Atlanta, where anyone in that number who wins the tournament would take home the Cup. Spieth, ranked No. 2 in the world behind Johnson, has finished first or second in four of his last six tournaments, including victories in the Travelers Championship and the Open Championship at Royal Birkdale. He is playing in the BMW Championship for the fifth time and has finished no worse than a tie for 16th. His best result was a tie for eighth in 2014 at Cherry Hills and he also was ninth last year at Crooked Stick. Spieth tied for 13th in 2015 and tied for 16th in 2013, both at Conway Farms, this year's venue.
