Europe captain Luke Donald has backed Rory McIlroy over his feud with Patrick Cantlay’s caddie Joe LaCava.
Donald said: “I was there on 18. I saw it unfold when Patrick made that putt, Joe was waving his hat.
“[McIlroy] politely asked Joe to move aside. He was in his line of vision. He stood there and didn’t move for a while and continued to wave the hat, so I think Rory was upset about that.
“It was a little off-putting because he still had to putt. And so Rory got upset, and I understand that. Rory felt like the line was crossed on the 18th green.”
