World number one Yani Tseng has booked her place in the second round of the Sybase Match Play Championship.
The 22-year-old Taiwan ace opened up her challenge at Hamilton Farm GC with a 3&2 victory over Marcy Hart, birdying the 15th hole before taking the 16th with par to set up a second-round clash with Jenny Suh.
Reigning LPGA champion Cristie Kerr won four of her first five holes on her way to a 3&2 win over Amanda Blumenhurst, while Suzann Pettersen won three of the final four holes to see off Natalie Gulbis, who could have extended their match had she not missed a 12-foot putt.
