Lowry and Bjorn completely out-shone their playing partner, Rory McIlroy who carded a 74 to finish on 2 over.

European Ryder Cup captain Paul McGinley finished on 2 under par.

Graeme McDowell and Padraig Harrington are still in the early stages of their opening rounds with McDowell on 1-under while Harrington is 1 over
