Two late bogeys spoiled a fine Open first round for KJ Choi on Thursday but the South Korean was still happy to continue his rich vein of form.
The Texas-based 36-year-old surged two shots ahead of the field with four birdies in the first six holes at a Carnoustie course drenched by rain and looked set to hang on to at least a share of the lead coming down the tough closing stretch.
Bogeys at the 15th and 18th holes, though, dropped Choi a stroke behind clubhouse leader Michael Campbell of New Zealand, the 2005 U.S. Open champion, with a two-under-par 69.
After battling against cold and damp conditions, Choi was happy with his morning's work, despite his late glitches.
"I still have a good feeling about my round," Choi told a news conference. "I only really hit one bad shot and that came at the 15th, where I was bunkered.
"Yesterday I practised in the rain purposely, anticipating there was there was going to be more today, so I didn't feel too concerned and found my rhythm well."
Choi's caddie is the highly experienced 55-year-old Briton Andy Prodger, who was by Nick Faldo's side when the Englishman won the 1987 British Open and 1989 U.S. Masters.
The two are now communicating much better after two years together.
Prodger told Reuters: "KJ's English has come on leaps and bounds this last year and we can communicate well now. My Korean seems to have got worse, so it's a good job."
Prodger is also happy with his returns from Choi's fine recent run which has seen the player earn over $2 million from victories in the Memorial and AT and T National on the PGA Tour. Caddies generally take a 10 percent cut of prize money.
Choi said of his relationship with Prodger: "I've won a lot of tournaments with Andy now. He makes me very comfortable and helps me to really focus during my round. He's like a big brother."
