Ireland's Padraig Harrington and Darren Clarke got off to flying starts at the Accenture world match play championship in California today.
Harrington made it through the first round for the first time in four attempts after a 4&3 victory over John Cook.
"I'm pleased with that," he said. "It's a long way to come and you don't want to be one of the 32 going home straight away. It feels like a wasted journey.
"I was more relaxed about it this time, though, and after my start I just played very solid golf.
Clarke, winner in 2000, beat South African Tim Clark by the same margin, but Colin Montgomerie suffered a 3&2 defeat to German Alex Cejka.
Justin Rose knocked out former Open champion David Duval after coming from two down to win on the 20th hole.
Duval had a real chance on the 19th hole. Rose was bunkered off the tee and bogeyed, but Duval three-putted, missing from six feet. Rose then struck his tee shot on the next to six feet and he made no mistake.
The English youngster meets defending champion Kevin Sutherland in the next round after the American eliminated fifth seed Sergio Garcia two and one.
Paul Lawrie lost 4&3 to Nick Price.
