Donald was fourth at the Masters in April and fifth in the Open two years ago, while Westwood has finished in the top three at five of his last seven majors.

F is for Faldo. Sir Nick is still the last Englishman to win the Open, way back when he clinched the last of his three Claret Jugs. He is also the last English winner of any major with his . He gave it a bit of a nudge at Sandwich eight years ago, finishing eighth, and was second there in 1993.

M is for McIlroy. Who else? Rory is the golf's new superstar and potentially one of the greats after . "Time will tell if he will become a multiple winner, but the one scenario I cannot imagine is that he will turn out to have been a one-hit wonder," said Nicklaus, 71. Attention on him will be fierce this week.

N is Greg Norman. The Australian great scorched around in 64 on the last day to beat Faldo by two shots to win at Royal St George's in 1993. It's also for Northern Ireland, the place that has spawned the last two US Open champions in McIlroy and .
