Harris English and Matt Kuchar shot a 6-under 66 in modified alternate shot play Friday to take the second-round lead in the Franklin Templeton Shootout.
English and Kuchar were at 21 under at Tiburon after opening with a 57 on Thursday in the scramble round. They won in 2013 in their first start together and finished second the last two years.
Wisconsin friends Steve Stricker and Jerry Kelly were a stroke back entering the better-ball finale Saturday. They shot 68. The 49-year-old Stricker is teaming with the 50-year-old Kelly for the record eighth time. They won in 2009, and Kelly also won with Rod Pampling in 2006.
Charles Howell III-Rory Sabbatini (69) and Kevin Chappell-Kevin Kisner (68) were 16 under. Defending champions Jason Dufner and Brandt Snedeker were seventh at 14 under after a 70.
Lexi Thompson and Bryson DeChambeau were 10th at 11 under after a 71. Thompson is the second woman to compete in the event, following Annika Sorenstam with Fred Couples in 2006.
