NORTON, Mass.

Golf ’s latest search for a breakout star has come to the quirky little laboratory of Bryson DeChambeau.

The 24-year-old physics major known as the “Mad Scientist” won his second straight event in the FedEx Cup playoffs on Monday, shooting a 4-under-par 67 at TPC Boston to win the Dell Technologies Championship by two strokes over Justin Rose.

It was the third win of the year for DeChambeau, who also won the playoff opener at Ridgewood and is guaranteed the No. 1 seed for the Tour Championship regardless of what happens in the third round. And he solidified his claim to be one of Jim Furyk’s captain’s picks for the American Ryder Cup team, where he would join the likes of Dustin Johnson, Rickie Fowler, Jordan Spieth, back-to-back U.S. Open winner Brooks Koepka and others who have staked a claim to follow Tiger Woods as golf ’s next big thing.

“People can put that title on me, but I’m not going to. Never will,” DeChambeau said after finishing at 16- under 268 to claim his second straight $1.62 million first prize.

“I’m just a player out here trying to do my absolute best. And I’ll say that every single time,” he said. “It is cool to have people say that to you. And it is an honor, it really is. At this moment going forward, though, I’m just going to keep going about my business and doing what I can do.”

DeChambeau is the first person to win the first two tournaments in the FedEx Cup since 2008, when a different points system allowed Vijay Singh to effectively wrap up the title before the final playoff event. DeChambeau still has work to do; he leads Johnson by almost 2,400 points, but the new system keeps the $10 million bonus in flux until the finale at East Lake Sept. 20-23.

Still, the back-to-back wins probably eliminate any doubt about the Ryder Cup team.

DeChambeau attended the last Ryder Cup, outside of Minneapolis — as a spectator.

“I wanted to experience it,” he explained. “I wanted to be a part of that atmosphere and get comfortable with that. So hopefully if I do make it this year that all things considered I’d be more comfortable when I got there. That was really the reason why I went there.”

A physics major at Southern Methodist, DeChambeau brings an unconventional but scientific approach to his game, peppering his comments with references to biomechanics and error tolerance and filling his bag with clubs that are all the same length (34 inches, or roughly the length of a 7- iron) so he would only have to master one swing.

The decision had its doubters, from potential college coaches who turned him aside to his father. (Now the elder DeChambeau uses one-length clubs, too.)

“I’ve had quite a bit of resistance,” DeChambeau said. “There’s only been a few people that have really helped keep pushing me in the right direction, saying ‘Hey, Bryson, you’re doing the right thing, Keep doing it. Just keep figuring things out.’”

He seems to have done that.

After starting the year at No. 99 in the world, DeChambeau moved to No. 7 with the win Monday, one spot past Rory McIlroy.

“He’s facing the biggest and best fields,” said Rose, who birdied three of his last four holes for a 68 and second place. “There’s a lot of conjecture about how he goes about it. But when he delivers as he is now, it just proves it.”

Opening the day one stroke behind leader Abraham Ancer, DeChambeau took control with three straight birdies to finish the front nine. Australian Cameron Smith closed the gap with a pair of late birdies, but DeChambeau answered with a birdie on No. 15 to keep his lead at two shots.

Ancer dropped three shots in a four-hole stretch on the back nine, hitting into a hazard and making bogey.
