BMW Championship: Marc Leishman wins, Justin Rose and Rickie Fowler second

Victory sees Marc Leishman jump three places to fourth in the Tour standings

Australian Marc Leishman saw off a late charge from England's Justin Rose to win the BMW Championship by five shots.

Leishman's lead was twice cut to two shots by Rose, before he eventually finished 23 under, five clear of the Englishman and American Rickie Fowler.

Rose shot a six-under 65 but a 67 from Leishman was enough to secure his third PGA Tour title in the penultimate leg of the FedEx Cup play-offs.

Leishman and Rose both secured spots in the season-ending Tour Championship.

England's Paul Casey also qualified for the lucrative finale but defending champion Rory McIlroy's faint FedEx Cup hopes, which rested on a top-four spot, are over.

The Northern Irishman finished 21 shots behind Leishman after a level-par round of 71 and slides from 51st to 58th in the FedEx Cup standings.

Only the top 30 qualify for the event, which starts at East Lake in Georgia, on Thursday.

McIlroy won a three-way play-off at last year's Tour Championship to take home $10m (£7.7m) in prize money.

Rose's performance saw him rise nine places to eighth while Casey qualified in 10th overall.

The four players who moved into the top 30 this week included Masters champion Sergio Garcia, who jumped from 34th to 25th in the standings thanks to his tie for 12th.

Five-time major winner Phil Mickelson came up just short in his bid to book a Tour Championship berth, finishing 34th in the standings.

How does the FedEx Cup work?

• Players pick up points throughout the regular season in each event they play. Most tournaments give 500 points to the winner

• The top 125 players enter the play-offs, which consist of four tournaments and where winning carries 2,000 points

• The field is whittled down to 100, 70 and then 30 for the final event, the Tour Championship

• Points are then reset, so that the number one player has 2,000 points, number two has 1,800 and number 30 has 115

• Points earned at the Tour Championship are added to that reset value and the player with the highest points total is named winner of the FedEx Cup
