A second-straight round of 68 saw Yani Tseng open up a four-shot lead at the halfway stage of the Ricoh Women's British Open at Royal Birkdale.
Tseng had produced a birdie-eagle finish yesterday to earn a share of the lead with Australia's Katherine Hull and the 21-year-old was again in fine form at the Southport course as she moved to eight under par for the championship.
The Taiwanese player finished with five birdies and one bogey to go four shots clear of Amy Yang, Cristie Kerr and Brittany Lincicome.
Yang produced a steady first nine with just the one birdie to turn with a 34 and then made a birdie on the last for a 37 to complete her second round with a one-under-par 71 to go to four under overall.
Kerr had a highly impressive day with six birdies accompanied by a bogey for a five-under-par 67, the best round of the day, while Lincicome recovered from two bogeys and a double bogey following the turn to record two birdies and an eagle in the last four holes for a one-under-par 71.
Norway's Suzann Pettersen and America's Christina Kim were among the day's biggest movers as their rounds of 68 saw them move to three under and two under respectively.
Petersen was joined at three under by Sun Young Yoo and Juli Inkster, while Hull's round of 74 saw her drop down the leaderboard to lie level with Kim on two under.
None of the Irish competitors in the field made the cut.
Royal County Down amateur Danielle McVeigh finished on nine-over after rounds of 74 and 79. Rebecca Coakley was 12 over with rounds of 77 and 79 while Martina Gillen was 13 over after two rounds of 79.
England's Laura Davies and Wales' Becky Brewerton were the best of the British challengers, but found themselves 10 shots off the lead at two over par.
