SAN FRANCISCO (AP) -- Jim Furyk is back at even par and back on top alone in the U.S. Open.

Furyk overcame a bogey on No. 1 and pared the next three holes Saturday. Fellow 36-hole leaders Tiger Woods and David Toms were 2 over through four and 1 over for the tournament.

Graeme McDowell and Nicolas Colsaerts also were tied for second at 1 over through five holes. Furyk held the clubhouse lead most of Friday until Woods and Toms closed strong with even-par 70s to join Furyk.

Phil Mickelson shot a 71 to go to 8 over for the tournament. He missed a putt to save par from about 7 feet on the 18th hole, but the crowd gave him some consolation by serenading him with ``Happy Birthday'' on the day he turned 42.
