Keegan Bradley has beaten Justin Rose in a sudden-death playoff to win the BMW Championship on Monday for his first PGA Tour victory in six long years.
Rose needs to win to displace American Dustin Johnson and become the 22nd man to be world number one since the rankings began in 1986.
Bradley shot 20-under 260 for the week with a 64 Monday - play was called off Sunday due to heavy rains - and moved from 52nd to sixth in the FedEx Cup standings.
The two-time FedEx Cup victor secured his spot in the Tour Championship with a top-10 performance at Aronimink.
"I'm glad it's over", Matsuyama said. "The belly putter was a tougher transition than I thought, and I kind of fell off the radar there for a little while".
Rose has won nine times on the PGA Tour, where he mostly plays, including one major, the 2013 U.S. Open.More news: Second patient diagnosed with monkeypox in England
Northern Ireland's Rory McIlroy, who trailed then-leader Rose by one shot after round three, finished fifth following a 68.
As usual, it crowded around Tiger Woods.
The final round was pushed back from Sunday to Monday because of constant rain that led to poor course conditions.
Bryson DeChambeau enters the Tour Championship atop the FedEx Cup points race. But he couldn't take advantage Monday, playing his first five holes in 3 over par and ending up with a 3-over 73 that had him depending on others.
Woods, who is projected to rise to No. 21 in the world, would have needed a final-round 62 to be part of the playoff.
Perhaps most important of all to Woods - the Tour Championship offers another chance for a victory, where he will need to defeat just 29 players. "And that's so huge for a player where I am at this point, because then I can play my way back into the top 50".More news: Barrow sends special delegation to Kofi Annan's funeral
Five-time BMW championship victor Tiger Woods mounted another vintage charge, but a late back-nine stumble has been the story of his comeback season from spinal fusion surgery.
"I've played a few tournaments where I came close at the end, but just didn't quite get the W", Woods said afterward.
The BMW Championship is the third of four FedExCup playoff events on the PGA Tour.
For Spieth, it's more than just missing the Tour Championship for the first time. Spieth also must qualify for the season finale to play the minimum 25 events this season or face a fine. This year he did not add a new event, and the Ryder Cup - which counts - will give him just 24.
"But obviously it's a big consolation being World No 1".
