Retief Goosen, Prayad Marksaeng, Phil Mickelson and Jeev Milkha Singh lead the World Golf Championships - CA Championship after all four signed for opening rounds of 65 to lie seven under par.
England’s Oliver Wilson missed a chance for a share of the lead at Doral with a disappointing final hole as Padraig Harrington made a welcome return to form on another good day for The European Tour contingent.
Wilson held a share of the opening round lead as he played the par four, 443 yard 18th hole but landed his second shot in water short of the green on the way to a double bogey six.
That left The Ryder Cup player with a first round 67 on day one of this 80 player, no cut event, two shots back of the leaders on the par 72, 7,266 yard Blue Monster course.
“Yes, very frustrating,” Wilson said of his final hole blunder.
“It is a tough hole, though, you know. I hit a great drive but I think that is the toughest pin on that green to be honest.
“I was more concerned missing the green right rather than left and I was just a bit in between clubs and didn’t really concentrate properly and hit a bad shot.
“It was a shame not to hole the putt for five, that would have been all right but I played all right, it was a good round apart from that so I’ll try and take that forward into tomorrow and the rest of the week.”
Ireland’s Harrington, The Open Championship and US PGA Championship winner, bounced back from a first round World Golf Championships - Accenture Match Play exit to Pat Perez two weeks ago and two missed cuts in his first four starts of the year prior to that.
The Irishman birdied three holes on his front nine and three more at the start of his inward nine on the way to six under par 66, one shot off the lead alongside American Nick Watney, Australia’s Rod Pampling and James Kingston of South Africa.
“I’m very happy,” Harrington said. “Obviously I have not had a great run of form so far this year so it’s nice to shoot a good score.
“I was probably a little more focused on my scoring this week than necessarily anything else so it’s nice to get out and shoot a decent number.
“I certainly didn’t hit the driver very well today but, again, my head seemed to be in the right place and I hit my irons well, short game was good.
“So all of those things added up to a 66.”
Joining Wilson in the clubhouse on five under were Louis Oosthuizen of South Africa, American Sean O’Hair, Argentina’s Andres Romero and Colombia’s Camilo Villegas, who had begun his day in the worst possible way.
Villegas, a big crowd favourite in Miami, gave his Latin American fans palpitations with an awful start to his round at the par five tenth, four putting from the fringe of the green for a bogey six before making amends over the next 17 holes.
Rory McIlroy got off to a great start and saw his round unravel slightly on the back nine.
The Northern Ireland 19 year old, a quarter-finalist at the WGC - Accenture in his first Stateside tournament as a professional and tied for 13th place in last week’s Honda Classic, eagled the first hole and was five under after 12 holes before bogeying the 13th and 14th.
McIlroy hit back with a birdie two at the 16th and finished four under with Americans Jim Furyk and Charley Hoffman.
World Number One Tiger Woods continued his comeback from knee surgery but was not firing on all cylinders in a solid if unspectacular opening round.
Woods, playing in his first stroke play event in nine months, carded a two bogey, three birdie round of 71 but was happy with his play if not a little perplexed.
“It was a little bit frustrating on those greens,” Woods said. “I hit so many putts that looked good.
“I thought I hit my lines and thought I had the right speed but they just didn’t go in.
“I have to be a little bit sharper, hopefully those putts go in and the score will be a little different.”
Luke Donald carded a three under 69 to make light of his wrist injury scare at the WGC - Accenture Match Play two weeks ago, while Ian Poulter, another of the eight Englishmen in the field this week, finished on the same mark.
