It seems that Jon Rahm has taken a liking to pranking Phil Mickelson. Not long ago, the Spaniard messed with the American's rangefinder, producing hilarious results. Ahead of LIV Golf Virginia, he did it again.The league's official X account posted a video in which Rahm admitted to switching four of Mickelson's rangefinders from yards to meters. As a true American, Mickelson is not a fan of the metric system, so he struggled to see the humor in it."Did they do the meters thing again?" Lefty said, at least partially annoyed.Rahm initially kept his cool, trying to deflect suspicion by pointing out that he wasn't the only European player there. However, he burst into laughter when influencer Grant Horvat tried a second rangefinder only to discover that it had also been switched.This took place during the preparation of the teams competing in The Duels Virginia, the second edition of the new LIV Golf event involving some of the most renowned golf influencers.Legendary golfer Phil Mickelson played with popular YouTuber Grant Horvat. The two have a long history of playing together and regularly create content as a team, facing off against professional golfers, stars from other sports, and other influencers.It was during one of these collaborations that they played against Jon Rahm, teaming up with NFL superstar Josh Allen. That's when the rangefinder prank involving yards being switched to meters was born.Since it was their first time, it was also [and hilariously] their worst. Not only did Mickelson and Horvat play with the rangefinder showing them incorrect distances for several holes, but they also couldn't figure out how to switch it from meters to yards afterward. It was unforgettable, for sure.Rahm played The Duels with Wesley Bryan, a former PGA Tour pro and popular YouTuber. The other three teams were Sergio Garcia and George Bryan, Bubba Watson and Luke Kwon, and Henrik Stenson and Fat Perez.Rahm and Bryan won the event, defeating Stenson and Perez in a playoff.More Golf: Keegan Bradley 'changes the story' on playing Ryder Cup captain
