Sour Brooks Koepka has issued an astonishing jibe at Ryder Cup adversary Jon Rahm who 'acted like a child'.

Team USA were smashed at the Marco Simone Golf and Country Club in Rome on day with Team Europe hitting a record-equalling five point lead over their rivals to leave captain Zach Johnson and his side with a huge barrier to overcome, as they look to end a 30-year wait for a Ryder Cup win on European soil. Masters champion Rahm eagled two of his three holes to help him and Nicolai Hojgaard see off Koepka and his partner world number one Scottie Scheffler.

The USA pair watched as a full point slipped away on the last hole and the PGA champion seemed to aim a jibe at his Spanish counterpart as he said: "Me and Scottie birdied, what did we say, 14, 15, 16, 17, 18, and then lost (that stretch) by two. So, yeah. I want to hit a board and pout just like Jon Rahm did. But, you know, it is what it is. Act like a child. But we’re adults. We move on."

On what USA can do to put it right, he added: “Honestly, we’ll be fine. We’re all grown-ups. We act like grown-ups. We’ll be just fine. Just got to play and see where it puts you.”
