Johnson recovers from shaky start to win BMW Championship

Updated: 

Dustin Johnson shook off a slow start and a surging Paul Casey to win the BMW Championship at Crooked Stick Golf Club on Sunday.

Johnson's three-shot lead to start the day quickly evaporated when he bogeyed two of his first three holes and Casey birdied holes two and three.

But the reigning U.S. Open champion rebounded with four birdies in his next five holes to separate himself from the scrappy Englishman.

With his third win of the season under his belt, Johnson - who finished at 23 under - will now head into the Tour Championship at East Lake atop the FedEx Cup standings.

The top 30 players in the standings advance.

Casey, with his second consecutive runner-up finish, snuck into the top five in the standings.

Any golfer in the top five claims the cup and the $10million prize with a win in Atlanta.

Casey shot a five-under 67 on Sunday to finish at 20 under. He made some noise late with an eagle on the par-five 15th hole, but Johnson matched him.

European Ryder Cup captain Darren Clarke has already made his picks, but he may wish he had waited like the United States' Davis Love III.

Casey is heating up at the right time and looks like a better prospect than fellow Englishman Lee Westwood.

Unfortunately for Rickie Fowler fans, he fell outside the top 30.

He is now at the mercy of past Ryder Cup experience and fellow players lobbying for him as Love makes three of his four captain's picks on Monday.

Roberto Castro finished third at 17 under after firing a five-under 67 in round four.

Castro started the tournament with back-to-back seven-under 65s, but he struggled to replicate that success on Saturday.

Yet, facing play-off elimination, Castro rebounded to secure a place at the Tour Championship.

Australian Adam Scott headlined a group tied for fourth at 12 under after shooting a one-under 71 in the final round.

Scott struggled with his putter throughout the week. However, he was still able to record his third straight fourth-place finish. He is now third in the FedEx Cup standings.

USA Ryder Cup hopefuls Matt Kuchar and J.B. Holmes also finished at 12 under with Charl Schwartzel and Ryan Palmer.

Schwartzel climbed to 30th in the FedEx cup standings, claiming the last spot in the season's finale.
