Lorena Ochoa will have to come from behind to win a fourth consecutive tournament.
Ochoa shot a 5-under 67 in the second round of the Ginn Open on Friday, leaving her three strokes behind leader Yani Tseng at Reunion, Fla.
Tseng moved to 12 under with a course-record 64. Suzann Pettersen (66) was 10 under, one shot ahead of Ochoa and Minea Blomqvist (66).
In the Verizon Heritage tournament at Hilton Head Island, S.C., Lucas Glover shot his second straight 66 to move to 10 under and take a one-stroke lead over defending champion Boo Weekley (64) at Harbour Town Golf Links.
Anthony Kim (67) was alone in third at 8 under, with two-time Verizon Heritage winner Stewart Cink (68), Cliff Kresge (66), and Stephen Ames (64) another shot behind.
