ST. ANDREWS, Scotland -- Louis Oosthuizen of South Africa has surged to the top of the British Open before first-round leader Rory McIlroy even tees off.
Oosthuizen bundled up in rain gear as he teed off early this morning at the Old Course. After four straight pars to start the round, he strung together three birdies in a row to push his score to 10 under.
The 21-year-old McIlroy will play this afternoon.
The Northern Irishman opened with a 9-under 63, tying the record for the lowest score in a major, and it was the fewest strokes needed to get through an Open round since 1993. All eyes will be on the weather. The morning started under a blue sky, but clouds moved in and it began raining harder than it ever did in the opening round.
