Lorena Ochoa birdied five of her last seven holes for a seven-under-par 65 on Saturday for a share of the lead with Sophie Gustafson after the third round of the CVS/pharmacy LPGA Challenge at Danville, Calif.
Ochoa, winless in 10 starts since taking the Corona Championship in her native Mexico in April, was four shots back after 10 holes, then used her strong finish -- including a 16-foot birdie putt on the 18th hole -- to match Gustafson at 16-under 200.
Gustafson, winless since 2003, had a 66.
Angela Stanford and Sun Young Yoo were six strokes back at 10 under after 69s, and Paula Creamer (69), Morgan Pressel (67) Leta Lindley (66) and Maria Hjorth (72) followed at nine under on the Blackhawk Country Club course.
Tom Pernice Jr. moved into position to become the 15th player to win his Champions Tour debut, shooting his second bogey-free five-under 67 to take a one-shot lead in the SAS Championship at Cary, N.C.
Dan Forsman and first-round co-leaders Denis Watson and Russ Cochran were tied for second at Prestonwood Country Club. Forsman shot a 68, and Watson and Cochran had 69s.
