Brooks Koepka was seen heckling his long-time rival Bryson DeChambeau with the pair on site at Trump Doral for the LIV Golf season-ending Team Championship in Miami.
DeChambeau and his Crushers team have the chance to become 2023 LIV Golf team champions on Sunday, as they battle it out with the 4Aces, the RangeGoats and Torque for top spot. Koepka's Smash GC meanwhile can only finish as high as high as ninth, after they were knocked out in the quarter-finals on Friday.
Smash's quarter-final defeat meant Koepka and co were forced to sit out play on Saturday, and on his day off the five-time major champion opted to enjoy some time in the on-course hospitality by the par-three ninth.

Partway through the semi-final matches, DeChambeau made his way to the ninth during his match with Cleeks GC captain Martin Kaymer. Despite sitting three-up in the match, the American pulled his tee shot left with Koepka watching on.

The pair have been known to share quite the rivalry in recent years, but DeChambeau took the dig well, chuckling away at Koepka's comments.
Having both joined the LIV setup, their feud appears to have eased off in recent months, especially when Koepka was seen offering DeChambeau a drink on the ninth in Miami just before his errant tee shot. Despite this, it did not stop Koepka teasing the idea of a multi-million dollar boxing match with his fellow LIV star this week.
After appearing on the 'BS w/ Jake Paul ' podcast, YouTuber-turned-boxer Paul quizzed Koepka on who his biggest rival in the world of golf is. Unsurprisingly the multiple major champion named DeChambeau, to which Paul replied: "Would you fight him like in a boxing match?"
Not ruling out a bout, the Smash GC captain went on: "Yeah, are you going to promote it?" With the ball now in Paul's court, the YouTube star pledged to put $2 million into the purse if the pair were to make it into the ring.
"I am down," Paul said. "I will put a $1 million purse up for each fighter, plus pay-per-view." Clearly keen on the idea, Koepka added: "I think we could make something happen."
