Darren Clarke and Graeme McDowell will line up on opposing sides at next week’s Tavistock Cup at Lake Nona in Florida.
Clarke is joining up with Tiger Woods to represent Isleworth while McDowell is once again on the Lake Nona team for the prestigious annual charity event.
But the Ulster pair won’t face each other directly in the two-day competition being play on Monday and St Patrick’s Day.
Clarke plays with Isleworth captain Mark O’Meara on the first day, taking on Mark McNulty and former Open champion Ben Curtis.
McDowell teams up with double US Open champion Retief Goosen against the big-hitting JB Holmes and Daniel Chopra from Sweden.
The format is a fourball medal matchplay with the team with the lower score over 18 holes winning
On Tuesday McDowell and Goosen take on Australian pair Nick O’Hern and Stuart Appleby in a fourball singles matchplay – each players score on each hole counts against both players on the opposing side.
Clarke plays with Chopra against McNulty and Ernie Els.
Tiger Woods plays with John Cook on the first day against Swede Henrik Stenson and American Chris DiMarco.
And he teams up with Charles Howell to play Stenson and Ian Poulter in what should be a very interesting match after the Englishman said last year that when he found his real form there would just be him and Woods battling it out ahead of everyone else.
Australian Robert Allenby makes up the Isleworth team while Master champion Trevor Immelman and England’s Justin Rose comple the Lake Nona line-up.
Isleworth won the event, which has been staged between the two Orlando clubs annually since 2004, last year when McDowell, playing with Stenson, halved their opening day match with Woods and Cook.
The series is tied at two victories each as the 2005 match ended in a tie in near darkness after three extra holes failed to separate the teams.
Attendance is strictly by invitation only and supporters are required to wear either red in support of Isleworth or blue for Lake Nona and anyone failing to comply will be denied entry.
Once on the course, however, spectators are able to walk the fairways behind the players in the same spirit as the Walker Cup.
