World number nine Rory McIlroy is in contention after carding a one-under-par score of 71, while England's Lee Westwood came in one over on 73.

Justin Rose and Ian Poulter fared poorly with four-over scores, while a two-stoke penalty saw Luke Donald finish on an even more troubling seven-over-par score of 79.
