Auckland golfer Ryan Fox has carded a one-over-par 72 in the first round at the World Golf Championships in Mexico.
Fox couldn't capitalise on a good start going two-under after seven holes. He bogeyed the eighth to make the turn one under par.
But bogeys on 11 and 15 proved costly, shooting two over the back to finish at one over par.
He sits in a tie for 35th, nine shots behind leader Rory McIlroy.
Entry to the tournament looked very unlikely just a week ago - but a win at the World Super 6 event in Perth catapulted him 19 places in the world rankings to 66th.
The event in Mexico is open to the top 50 in the world, but Fox was named as an alternative after a number of withdrawals.
The 32-year-old arrived in Mexico City at 8:30pm local time, just 16 hours before his tee time.
There is no cut in the event - with the last place finisher taking home over US$50,000.
