Paul McGinley could wreck Padraig Harrington's bid to retain the Order of Merit.
Trailing Ernie Els by €217,295, Harrington could have enough to become No 1 again if he shares third place with just one other player.
A three way tie for third would be worth just €206,533 - not be enough to catch Els - and McGinley does not event want to think about the prospect of being the man who costs Harrington his crown.
Grimacing at the thought, McGinley said: "Oh crikey, I don’t know about that. But I didn’t screw it up for him at the Open. By Sergio’s account I actually helped him."
Garcia hinted at Carnoustie that McGinley's slow coach play on the 72nd hole left him waiting too long to hit his approach, which he bunkered.
But McGinley revealed that he has sorted out his differences with the Spanish star.
He said: "I've spoken to Sergio and Sergio didn’t mean it the way it came out. He meant the guy raking the bunker took forever.
"And when he’d finished raking one, he walked across and raked the other. That’s what he was referring to. He wasn’t referring to us in front.
"They hadn’t seen us all day. We were at least a hole ahead of them all day. They only caught us on 18 when we were watching Padraig hole out."
