Spieth entered the final round at Glen Oaks Club on Sunday with a three-stroke lead on Johnson, but the latter’s 4-under 66 thanks to an 18-foot putt to make par on the finale hole tied him with Spieth and forced a playoff. The 24-year-old — who won the British Open in July — gained a one-shot lead over Johnson with a birdie on Hole No. 14 before Johnson countered with a birdie on the 15th.

Johnson — the 2016 U.S. Open champion — hit an amazing 341-foot shot in his return to the 18th hole during the playoff before tapping in a short birdie putt to earn his fourth victory of the year.

The first playoff hole began with Spieth hitting a respectable 315-foot drive down the fairway. However, the young Texan then couldn’t make his approach shot stay on the green. He followed the iron approach with a birdie attempt from the fringe, but he couldn’t sink it to match Johnson.

Both Spieth and Johnson finished at 13-under 267 on Sunday.

Johnson’s victory marked his first since he injured his back while falling down stairs at Augusta to miss the Masterst Tournament in April. He had won three straight tournaments against strong fields until that injury.

“I feel like the game is finally back in form like it was before the Masters,” Johnson said.

Sunday’s victory also marked Johnson’s second Northern Trust trophy and fourth FedEX Cup Playoff title. The 33-year-old North Carolinian — who is now No. 1 in the world — took home $1.5 million on Sunday.

Spieth is ranked No. 2 in the world.

Bubba Watson won his second Northern Trust Open in three years on Sunday, and revealed afterward that he passed a kidney stone earlier in the same week.

Bubba Watson Passes Kidney Stone Before Northern Trust Open Win

This is the second time Watson, 37, has passed a kidney stone in the last five years: the first time was in New Orleans, after he took a bathroom break on the 16th hole. This time, it happened between Pebble Beach and Riviera.

“So Sunday, I missed the cut at Pebble. And that Sunday morning playing with the kids, I had to go take a bathroom break and same thing: red liquid came out. I said, ‘This ain’t right,'” stated Watson.

“So we called the doctor, we called the tournament here. They set me up with a place. I landed on Monday morning, went, did a CT scan and 30 minutes after the CT scan, again, just downing water, thinking it’s going to be the same thing. Five years ago, he said there was one more in my system and obviously it decided this week. My baby came out, I guess. I’m already a head case, so my thoughts of seeing red liquids coming out, I thought I was dying, basically, without pain.”

Watson won the Open by one stroke over Adam Scott and Jason Kokrak. He recorded five birdies to post 15-under-par for the tournament. In the same busy week, Watson also filmed a cameo for his favorite show ‘Girl Meets World’ and attended the Saturday night Clippers-Warriors game, all in Los Angeles.

He also said he received a text message from Warriors star Steph Curry shortly before his tee time on Sunday, which said that he wants to teach Watson’s son Caleb how to shoot a basketball.
