Oosthuizen battling hard

Louis Oosthuizen is battling hard to maintain his lead in the third round of the Open Championship at St Andrews.

Oosthuizen held a five-shot lead over 1989 champion Mark Calcavecchia at 12 under when the delayed second round was completed this morning, the South African having made the most of his early start on Friday before the bad weather struck.

Oosthuizen unsurprisingly made a nervy start after a wait of more than 28 hours since completing his second round and his approach to the opening hole finished around 40ft beyond the flag, from where he three putted after charging his first effort six feet past. A run of four pars settled the 27-year-old down, but his lead was down to two shots.
