In 2021, Brooks Koepka and Bryson DeChambeau had a widely publicized feud that left the golf world stunned. That same year, 45-time PGA Tour winner Phil Mickelson was asked to comment on the epic rivalry, and he said that it was good for the game.Koepka and DeChambeau’s rivalry initially flared up in 2019 when the former disapproved of the latter’s pace of play during the Dubai Desert Classic. They clashed heads again in the 2021 PGA Championship, and the feud reached an all-time high when fans began to heckle DeChambeau with “Brooksie” heckles.During an episode of the live Pat McAfee show in August 2021, 11-time European Tour winner and six-time major champ Phil Mickelson spoke about the feud. He stated that it was a brilliant way to grow the game of golf.“I think it's brilliant for golf. I think it's incredible, and I like and respect both players very much. I think it's something that has helped golf transcend beyond just the golf page and move more into the sports world. It's been great for both of them individually as well.” [28:30]“I just think it's been terrific. They've brought a lot of awareness to the game of golf, along with great storylines and a lot of interest. I think it's been fabulous,” he added.Later that year, Bryson DeChambeau and Brooks Koepka reached a cease-fire and squashed their differences. They both competed for Team US in the Ryder Cup, helping the team to claim the victory with 19-9 over Team Europe. Afterwards, the two players hugged it out while holding the trophy and singing.A year after winning the Ryder Cup, DeChambeau and Koepka both joined LIV Golf, the Saudi-backed league, further strengthening their newfound common ground. In 2024, DeChambeau commented on the rivalry, saying they were past it and now respect each other.Meanwhile, Koepka echoed the thoughts, saying he was initially wrong about DeChambeau and the feud was over.Phil Mickelson congratulates Scottie Scheffler after 2025 PGA Championshp victoryOn May 18, 2025, Scottie Scheffler claimed his third major championship title at the PGA Championship.
