British Open - Friday 12 noon (BST)

Ricky Barnes decided to get his fourth-round collapse over early, with a double-bogey on 14 and a bogey on 15. Louis Oosthuizen is giving interview after interview celebrating his second-round 67 and his three-shot lead. And now some parts of the course are getting rain while others are in bright sunshine. I can't imagine living in this weather all year:

1. L. Oosthuizen (RSA): -12 (36 holes)

2. R. McIlroy (NIR): -9 (18)

3. P. Casey (ENG): -8 (31)

T4. M. Calcavecchia (USA): -7 (36)

T4. P. Hanson (SWE): -7 (32)
