Bryson DeChambeau's quirky scientific methods are starting to win over fellow PGA Tour players with the young American dominating the first two FedEx Cup playoffs events.
DeChambeau has pocketed US$3.2 million (AU$4.5 million) from runaway victories at the Northern Trust and Dell Technologies events, which have guaranteed his No.1 FedEx Cup ranking through to the Tour Championship finale.
The Californian's often-ridiculed methods include using a set of irons all the same length, instead of featuring the traditional half-inch gap.
DeChambeau, who studied physics at university, also individually tests the centre of gravity of his golf balls.
Ahead of this week's BMW Championship in Philadelphia, Marc Leishman admitted DeChambeau's hyper-analytical approach to golf is starting to make his peers curious.
"I think as far as his clubs go ... yeah, I have definitely thought about it (because) it certainly works for him," Leishman said of DeChambeau, who also won the prestigious Memorial Tournament in June.
"I wouldn't look for anything to change with Bryson; I feel like he's really figured out what he's doing right now." – Jordan Spieth
DeChambeau owns four US Tour titles since July last year – more than superstars Jordan Spieth and Rory McIlroy combined during that span.
Three-time major winner Spieth says he is in awe of DeChambeau's relentless pursuit of perfection.
"He's got a way about his game that is fine-tuning to the extreme within different parts of his swing," Spieth said.
"I wouldn't look for anything to change with Bryson; I feel like he's really figured out what he's doing right now."
The 24-year-old DeChambeau is in the driver's seat for the FedEx Cup crown.
Regardless of his result in Philadelphia, he will take the No.1 seed into the Tour Championship in two weeks.
The top-five seeds at Atlanta's East Lake Golf Club are guaranteed the US$10 million FedEx Cup bonus if they win the Tour Championship.
