Jon Rahm claimed a share of the lead at the Scottish Open and Rory McIlroy missed the cut as the two European Ryder Cup stars found themselves at the centre of a bizarre incident at the Renaissance Club in North Berwick.
Rahm and McIlroy were playing with Justin Thomas when, on the 10th hole, a spectator walked on to the tee and removed the cover from the Northern Irishman's driver before taking a couple of practice swings with an iron.
"I was surprised. Everyone saw what happened on TV," McIlroy said, as quoted by BBC Sport. "It was handled efficiently and everything was okay. I had no idea who it was."
Rahm claimed the man, who Police Scotland said was taken to hospital after being ejected from the course, smelt of alcohol and added: "I don't think any of us understood what was going on.
"It didn't put anyone off. If anything it put a smile on our faces. It will be a pretty good story to tell in the future."
Rahm's sparkling recent form, which secured the U.S. Open title last month and sees him riding high as world number one, is also shaping up into a pretty good story to tell.
The Spaniard carded eight birdies in a 65 to follow his Thursday 66 for 11 under overall. Belgium's Thomas Detry matched Rahm's scores and England's first-round leader Jack Senior made it a three-way tie at the top.
Lee Westwood stormed into the clubhouse, going eagle, birdie, birdie over the final three holes and is a shot behind the leaders alongside Matt Fitzpatrick and George Coetzee, while Thomas and Ian Poulter are in a group of four players on eight under.
Inebriated interlopers were not the end of McIlroy's concerns, however, as he could only card a level par 71 on Friday, leaving him one under for the tournament and a shot below the cut line.
