Rory McIlroy also ‘went at’ Brooks Koepka’s caddie, Ricky Elliot, after Ryder Cup car-park bust up, claims Fred Couples

Rory McIlroy reportedly ranted at not one, but three Team USA caddies as his fury on Day Two of the Ryder Cup refused to cool down even after the Northern Irishman returned to the team hotel.

Team Europe’s talisman lost his cool on the car park at Marco Simone following Saturday’s fourball session, when he was seen furiously screaming at another US caddie, Jim ‘Bones’ MacKay before being bundled into a BMW 4×4 by teammate Shane Lowry.

McIlroy’s outburst came after he was left raging when LaCava, Cantlay’s caddie, stood in his line of vision twirling his cap as he attempted to line up what would have been a match-saving putt on the 18th.

The 34-year-old’s frustration was directed at MacKay as he claimed Justin Thomas’s bagman was ‘just the first American I saw after I got out of the locker room,’

McIlroy admitted that Tiger Woods’s caddie had been in the ‘wrong place at the wrong time’ and he texted him the morning after to apologize.

However, it seems Bones wasn’t the only American caddie to get an earful from the European leader as he also let rip at Ricky Elliot, an Irishman who loops for Brooks Koepka, according to Team USA vice captain, Fred Couples.

‘He was yelling at Bones,’ Couples said, via Golf.com, ‘which is disrespectful with his wife standing a foot from him saying words that shouldn’t be said. Now, I’m on Rory’s side too — because I love Rory McIlroy to death — but when you’re incensed and you want to fight, you’re going to say things. Is that disrespectful?’

Couples added that Elliott told him that McIlroy ‘went at me in the middle of the foyer at the hotel.’

Fans at a raucous Marco Simone had spent the round taunting Cantlay by waving their hats in the air after an earlier report claimed he was not wearing a cap as a form of protest against not being paid for competing in the tournament – something he has adamantly denied, suggesting it was instead because he wanted to avoid tan lines ahead of his wedding Monday.

When Cantlay sank a stunning 30-footer to put the US on the brink of winning his match with Wyndham Clark against McIlroy and Matt Fitzpatrick he responded by mimicking taking off a hat – while bag man LaCava joyously twirled his in McIlroy’s line of vision.

‘I asked him what was said,’ Couples said on his radio show. ‘He said Rory looked at him and said, ‘Mooove.’ And he made the ooo last a little longer.

‘And Joe replied, ‘Relax, Rory.’

LaCava also exchanged heated words with Lowry, who was greenside.

Couples was among the members of the US team, including Thomas, Jordan Spieht, Max Homa and Collin Morikawa, who waved their caps from the side of the green to celebrate Cantlay’s putt – all while LaCava’s spat with McIlroy ensued.
