Donald leads at Hilton Head

Luke Donald is on course to become world number one after a second-round of 65 moved him into a one-shot lead at The Heritage at Hilton Head.

The 33-year-old is currently ranked number three but, with current rankings leader Martin Kaymer having a week off and Lee Westwood playing in a tournament worth fewer ranking points in Indonesia, a win in south Carolina would move Donald to the head of the standings.
