Park led on 13 under par and was in the final group out yesterday, but he instantly dropped back as he bogeyed the first hole and Thailand's Thammanoon Srirot birdied it to move clear at the top of the leaderboard.

But that was as far as it went, with play halted and called off for the day. The event will now to be decided over 54 holes.

Elsewhere, Tiger Woods, winner of his first two tournaments this year, was relieved just to survive the halfway cut at the Nissan Open in Los Angeles. Caught without an umbrella in his bag when a rainstorm hit the Riviera Country Club, Woods missed putts of five and eight feet for a 74 that left him on one over par. Those two errors dropped the flu-suffering world number one from 54th to 72nd.

Only the top 70 and ties qualify for the final two rounds, but there were still a number of players to finish and mistakes by others let him back in.

While South African Rory Sabbatini roared past Britain's Justin Rose into a four-shot lead . . . joint firstround pacesetter Rose could add only a 74 to his opening 64 "It's been a while since I was caught out like that, " Woods said. "It was cold and wet and I was just trying to hit it solid.

I drove it great, but hit my irons terrible and had a hard time on the greens."

Dubliner Paul McGinley had his second successive 70 and lies at two under, but Graeme McDowell missed the cut. "I played good . . . lots of greens, lots of fairways . . .

and while it's not world-class it's something to build on, " McGinley said. "I've been in the game long enough. If you have two or three wins in a year it's an unbelievable year.

That means there are 27 events you're not winning and the key in them is to build up for the weeks when you are hot. I've made the cut again and have an opportunity for a good finish. It helps to reach the buzz."

McDowell is set to play either Woods or Vijay Singh in next week's world match play in San Diego depending on whether Retief Goosen pulls out. "I'm very close, " he said after his round. "I'm just having a few teething problems with equipment, but it's getting better every week."
