Drama peaked between the two last week at The Northern Trust, but both DeChambeau and Koepka appeared on SiriusXM PGA Tour Radio on Tuesday to defuse any perceived animosity.
"Let's be honest, we know who would win that fight and it's not me. Let me tell you right now - he'd kick my ass," DeChambeau said, according to Golf.com's Dylan Dethier.
"You've got that right," Koepka added.
The golf world's speculation was kicked into overdrive last week when DeChambeau approached Kopeka's caddie on the practice green and told him to make sure that Koepka makes any slow-play comments "to my face." DeChambeau has received heavy scrutiny from Koepka - and others - over a pair of viral videos last week that showcased how long he can take to complete his shot process.
For what it's worth, DeChambeau is listed at 6-foot-1, 205 lbs, while Koepka is a near-identical 6-foot, 205 lbs.
