GLADSTONE, N.J., May 17 (UPI) --
Jodi Ewart turned in one of the upsets on the first day of the Sybase Match Play Championship Thursday, eliminating defending champ Suzann Pettersen
Ai Miyazato, Paula Creamer and Brittany Lincicome, all of whom were among the tournament's Top 10 seeds, also suffered first-round defeats.
Ewart recorded a 3-and-1 triumph over Pettersen at the Hamilton Farm Golf Club, rallying after the defending champion had won the first two holes.
Mariajo Uribe defeated Miyazato 2-up in the final match of the day, Jennifer Johnson was a 2-and-1 winner over Creamer and Ryann O'Toole ousted Lincicome 2-and-1.
World No. 1 Yani Tseng survived with a 1-up win over Jeong Jang, who missed a 6-foot putt on the 18th hole that would have extended the match.
Tseng will meet Katie Futcher Friday after Futcher defeated Chella Choi 4-and-3.
Among the 32 winners Friday were Cristie Kerr, Na Yeon Choi, Jessica Korda, Morgan Pressel, Stacy Lewis and last year's runner-up Angela Stanford.
Michelle Wie was defeated by Mina Harigae 3-and-2.
