(CNN) -- U.S. Ryder Cup star Dustin Johnson carded a final round two-under-par 69 to claim a one-stroke victory in the BMW Championship on Sunday.
Johnson finished on a 72-hole total of 275, to finish one stroke ahead of Paul Casey (69), who missed out on qualification for the European Ryder Cup team after failing to get one of captain Colin Montgomerie's three wildcard picks.
Another Ryder Cup player, Matt Kuchar, along with KJ Choi, Ryan Moore and Kevin Na all finished another stroke behind.
But there was disappointment for world number one Tiger Woods, who needed to finish in the top five to seal his place in the Tour Championship, the final tournament in the FedEx Cup playoff series.
Woods carded a one-under-par 70 to tie for 15th place, a position not enough to claim one of the 30 spots available for the series finale which boasts a $10m bonus for the winner of the competition.
It's the first time Woods has ever failed to qualify for a tournament and he simply told reporters: "That's just the way it is. I didn't play well early in the year, and I didn't play well in the middle of the year."
Woods will now be out of action until taking his place in the Ryder Cup team at Celtic Manor on October 1.
A birdie on the 17th hole ensured Johnson edged ahead of Casey for his second tournament win of the season.
It also erased the bitter memory of his disappointments in majors this season; losing a three-stroke final round lead in the U.S. Open and then being penalized two strokes for grounding his club in a bunker when in sight of victory in the U.S. PGA.
Johnson is also up to second place in the FedEx series, while Casey has moved into fifth. Kuchar leads those standings after his tie for third position.
