Irish golfer Graeme McDowell shares lead at Chevron World Challenge

It's looking like a 'three-horse race,' says McDowell

Graeme McDowell shares the lead with Y.E. Yang going into Sunday’s final round of the Chevron World Challenge at the Sherwood Country Club in Thousand Oaks, California.

McDowell, who was only invited to play in the tournament on Monday after Tiger Woods pulled out, carded a six under par 66 to go ten under par for the tournament.

Overnight leader Padraig Harrington is hot on the joint leaders' heels, a third round 70 leaving him on nine under par for the tournament.

However, Harrington was not happy with how his round went:

"Something wasn't right today. I played great yesterday, played good the first day, played horrible today. Who know what will happen tomorrow?" he told press afterwards.

For McDowell,  who double bogeyed the sixteenth on the way in, a win could get him back in the top 50 – he is currently ranked 55th – and possible inclusion into the field for the 2010 U.S. Masters.
