VIRGINIA WATER, England (AP) U.S. Open champion Angel Cabrera led Paul Casey by one hole Friday halfway into their 36-hole match in the second round of the World Match Play Championship.
Earlier, Stenson and Romero completed first-round wins in their delayed matches, which were held up for two hours by heavy fog Thursday morning.
Cabrera took a three-hole lead after hitting two birdies and an eagle on the first fifth hole. His eagle at the long 4th came after a 5-wood second shot rolled to within one foot of the flag.
Casey, the defending champion, won the 6th and 7th and both players made another four birdies during the rest of the round, without dropping a shot.
Els won the first two holes against Romero with birdies, then bogeyed the next two to lose them both.
Then he took control, pulling away with four birdies in the last seven holes on the back nine.
Stenson was even better, getting birdies at five of the last seven holes against Hansen, who defeated Padraig Harrington Thursday.
Mahan, who upset Justin Rose Thursday to become the only American player in the second round, took the lead at the fourth against Soren Hansen and gradually pulled away.
In their suspended first-round matches earlier Friday, Stenson eliminated Woody Austin 1 up after making a 15-foot birdie putt at the last hole. They were all square after 35 holes of their match Thursday when darkness brought play to a halt.
Romero and Sweden's Niclas Fasth resumed on the 15th with the Argentine player leading by two holes, and he won the 16th with a 10-foot birdie to wrap up the match 3 and 2.
"Unfortunately for me, I gave away too many early holes,'' said Austin, who trailed by five after 13 holes Thursday. "But the momentum was definitely on my side on Thursday night.''
