YANG MEI, Taiwan (AP) - Suzann Pettersen shot a 7-under 65 to share a two-stroke lead with Inbee Park of South Korea halfway through the Taiwan Championship on Friday.
They were at 10-under 134 at the Sunrise Golf and Country Club.
Defending champion Yani Tseng (69), the local favorite, slipped into a tie for third with Catriona Matthew of Scotland (66).
Pettersen, who won in South Korea last weekend beating Matthew in a playoff, recorded seven birdies, four on her last six holes, to catch first-round leader Park.
The Norwegian with eight career victories said a light mood and aggressive game helped her to pull ahead near Taiwan's northwest coast.
``I figured it's time to kind of shift to the fifth gear, and it's nice when the body reacts to your kind of mind game,'' Pettersen said.
Park, who shot a 69, sank four successive birdies to reach 10 under after nine holes, bogeyed the 17th but reclaimed the lead with a birdie on the last.
Matthew started better than she finished, while Tseng struggled to get going after a bogey on the seventh, managing birdies only on Nos. 13 and 18 to stay in contention.
``The crowd goes like crazy,'' Tseng said, describing the reaction at the 18th hole. ``It gave me goose bumps.''
