VIRGINIA WATER, England (AP) Defending champion Paul Casey and six-time winner Ernie Els reached the second round of the World Match Play Championship at Wentworth on Thursday.
Casey, the top-seeded player, beat Jerry Kelly 3 and 2. Els easily defeated Colin Montgomerie 6 and 5.
"I feel fortunate to be through to the next round," Casey said. "Jerry could have taken the match further or even won it but I did get fortunate and he missed a couple of putts."
"There will be a lot of soul-searching as to why I'm playing well and couldn't produce it today," said Harrington, the British Open champion who bogeyed three of the first five holes in the morning. "Losing in the first round is very disappointing because I was thinking of going all the way."
Also, U.S. Open champion Angel Cabrera had 11 birdies to beat Retief Goosen 6 and 5.
Two matches did not finish because of a two-hour fog delay in the morning.
Henrik Stenson and Woody Austin were all square after 35 holes, and Andres Romero led Niclas Fasth 2 up after 32 holes. They will be completed Friday morning before the second round.
Els jumped out to a quick lead over Montgomerie.
"I drove the ball very, very well, as good as I've driven it in a while around Wentworth," the South African said. "We both played scrappy this afternoon, but it was good enough to get through."
Montgomerie had little good to say about his round.
"I played rubbish, rubbish," the Scotsman said. "It was awful. I three-putted the first green and it set the tone for the day.
"I spent three days practicing my putting in the rain then I three-putt the first green. End of day. That was it. The worse I played, the better he became."
