Ewart shocks champion Pettersen
Jodi Ewart caused an upset in the first round of the Sybase Match Play Championship as she knocked out defending champion Suzann Pettersen.
England's Ewart, ranked 210th in the world, found herself two down after two holes against the world number three in New Jersey, but was back on terms with the Norwegian after the fifth.
The 24-year-old took the lead at the 12th and never gave it up from there, claiminga 3&1 victory.
Ewart told the LPGA Tour's website: "I wanted to get off to a really good start and that didn't really happen that well.
"After two I was like, I am going to get absolutely thrashed.
"So then when we both parred number three, it just really calmed me down."
She added: "On paper I'm not supposed to win at all, so there's no pressure on me.
"I just went out there and played really fearless golf because I was attacking pins."
World number one Yani Tseng battled into the second round with a one-up victory over Jeong Jang.
Tseng was four up through six against Jeong Jang, but after 15 it was all square once again.
Tseng then took control again with a par at the 16th, before splitting the last two holes to advance.
She said: "It's a tough day for me today and I feel I'm pretty lucky to win a match today.
"Hopefully tomorrow it's another new day and hopefully tomorrow I'll drop more putts."
Ewart was the only Briton to advance as Catriona Matthew was upset 3&1 by Candie Kung, while Karen Stupples lost 4&3 to Sophie Gustafson.
Gustafson of Sweden is next up for Ewart.
Other notable players to fall included Ai Miyazato, Paula Creamer and Brittany Lincicome.
