Graeme McDowell looks to make it a 1-2 for Northern Ireland and is currently a 4/1 chance, with fellow golfer Lee Westwood the 7/1 third favourite.
David Haye is 40/1 with Ladbrokes.com and World Darts favourite Phil Taylor also a 40/1 shot.
Alex Donohue of Ladbrokes said: “Tony McCoy looks set to cost us again. But we would be paying out with a broad smile across our face as he would be an exceptionally worthy winner. He continues to be racing’s biggest asset. ”
