The first FedEx Cup playoff event is in the books. Jason Day captured The Barclays at Plainfield Country Club after a tremendous final round on Sunday.

Day shot a 62 (8-under) in the final round to run away with the victory. It was his second consecutive PGA Tour triumph and came just two weeks after his win at the PGA Championship. He was 19-under par for the tournament and defeated Henrik Stenson (-13), Bubba Watson (-11) and Zach Johnson (-10), who were his next closest opponents.

Last year's champion, Hunter Mahan, missed the cut at the 2015 event thanks to a first-round score of 78. He shot a 71 in the second round, but it wasn't enough to help him climb back into contention.

Day took home $1.5 million of the $8,250,000 purse and earned 2,000 FedEx Cup points to pull ahead of Jordan Spieth. Here are the current FedEx Cup standings:

Jason Day - 4,459 points

Jordan Spieth - 4169 points

Bubba Watson - 3,167 points

Henrik Stenson - 2,152 points

Zach Johnson - 2,049 points

Yesterday marked the fourth PGA victory for Day this season and he joined Jordan Spieth as the only other golfer to win four times this year, according to Nick Menta of The Golf Channel. The two stars will compete in the final three events (all FedEx Cup playoff tournaments) of the 2014-2015 season, including the Deutsche Bank Championship (Sept. 4-7), the BMW Championship (Sept. 17-20) and the Tour Championship (Sept. 24-27).

Since missing the cut at The Memorial in early June, Day has finished tied for ninth at the U.S. Open, tied for fourth at the British Open, first at the RBC Canadian Open, tied for 12th at the WGC-Bridgestone Invitational, first at the PGA Championship and first at The Barclays.

His tied for fourth effort at the British Open really helped him learn a lot.

"It was just the way that I felt calm, that no matter what happened, everything was going to be OK and you were just going to keep fighting and not give up," he told Jason Sobel of ESPN. "Ever since then, I just felt a lot more calm on the golf course. I felt like it was my time. Like mentally I felt like, you paid your dues, now it's time to go out and win tournaments. That's kind of the way it felt for me, especially coming out in final rounds."

The 27-year-old Australian will go for his third consecutive win at the Deutsche Bank Championship this week.
