PITTSFORD, N.Y. » Top-ranked Yani Tseng shot a 2-under 70 to take a one-stroke lead over Pat Hurst after the second round of the LPGA Championship, the tour’s second major of the year.

Battling a torrential downpour then a steady drizzle for nearly half her first nine holes, Tseng followed her first-round-best 66 with a grinding performance that put her at 8 under overall. She won the LPGA State Farm Classic two weeks ago for her second LPGA Tour victory of the year.

Hurst shot a 67 in the morning before the heavy rain.

Honolulu’s Michelle Wie shot her second even-par 72 and is eight shots back, tied for 38th. Wie started on the back nine and had three birdies to go 3 under. But she had a double bogey on the par-3 fifth hole and a bogey on the seventh.

Morgan Pressel, Minea Blomqvist, and Hee Young Park were 6 under after 69s.

Huston, Wiebe tied at 65

John Huston and Mark Wiebe shot 7-under 65s to share the lead after the first round of the Dick’s Sporting Goods Open at Endicott, N.Y. Huston had seven birdies on a bogey-free day, nearly making eagle at No. 18 when his second shot at the par 4 hit the flag and stayed out. The tap-in birdie tied him with Wiebe, who also had seven birdies and no bogeys as he began his drive to win his second straight event. Wiebe won at Rock Barn two weeks ago.

2 tied in Munich

South Africa’s George Coetzee birdied four of his last six holes for his second straight 5-under 67 and a share of the lead with Henrik Stenson in the BMW International Open at Munich.
