SHANGHAI (Reuters) - South African Branden Grace shot a sparkling nine-under 63 to take a one-shot lead in the first round of the WGC-HSBC Champions on Thursday while Rory McIlroy overcame a bout of food poisoning to finish five strokes back.
World number three McIlroy had been bedridden for two days and missed out on practice rounds at the Sheshan Golf Club in Shanghai. While he did not look back to full health he still carded a 68 to occupy a tie for 16th place.
It was a score matched by world number two Jordan Spieth, defending champion Bubba Watson and South African major winners Charl Schwartzel and Louis Oosthuizen in an opening round delayed by 30 minutes because of heavy fog.
When the fog lifted it was Grace who saw the hole clearest, the 27-year-old rolling in a short birdie putt on his last, the ninth, to break out of a four-way tie at the top of the leaderboard.
Grace took advantage of the soft conditions following heavy rain on Wednesday evening to fire some pinpoint irons in his bogey-free round at the $8.5 million event, which Watson won with an 11-under total last year.
“The ball-striking was probably the best it’s been in a long time so that was the main key today,” Grace told reporters.
“There was barely a breath of wind out there and the golf course is playing probably as easy as it could be playing.”
American Kevin Kisner, Australian Steven Bowditch and Dane Thorbjorn Olesen fired 64s to sit one back of the world number 22.
American Dustin Johnson, chasing his second WGC title of the year after his Cadillac Championship win in March, produced another dazzling display of long hitting as he carded a 65.
The 2013 champion was also inches away from a hole-in-one at the 197-yard fourth.
Seven-under was good enough for a share of fifth alongside compatriot Patrick Reed and England’s Danny Willett who is second in the European Tour’s Race to Dubai behind McIlroy with two events remaining after this week.
McIlroy’s participation was in doubt due to his illness but he loaded up with antibiotics and painkillers before producing a six-birdie effort.
The round could have been even better but for a double bogey six on his sixth hole and a cold putter.
“I’ve lost 10 pounds since being here. I can’t remember the last time I was this light. But hopefully I’ll have a couple of good meals over the next couple of days and rehydrate and I’ll be feeling a lot better,” McIlroy said.
“It was a score I thought could have been a lot better but considering the position I was in this time yesterday it’s not a bad start.”
Double major winner Spieth scrambled well in his 68, his first outing since last month’s U.S. Presidents Cup win, overcoming a lost ball at the par-three 17th following a wild tee shot.
“I hit one or two stray shots but that back nine, two-under the last three, was fantastic. I stole a couple there and I‘m pleased with four-under,” the U.S. Masters and U.S. Open champion said.
