More drama between Brooks Koepka and his fans ... TMZ Sports has obtained video showing the golf superstar snatching a phone from a guy who was trying to talk to him after one of his rounds over the weekend.
We're told the incident went down shortly after Koepka beat Jon Rahm at the WGC-Dell Technologies Match Play tournament in Austin, Texas on Saturday.
In the video, you can see a fan put his phone near Koepka's face as the 28-year-old was carting around the course with his wife, and asked him about beating Rahm.
