Elena Baltacha (100/1 to win tournament on outright coupon) caused an upset at the BNP Paribas Open to make in into the third round but Justine Henin will not join her in the draw.

The British qualifier beat seventh-seed and Australian Open semi-finalist Li Na in the second round 7-6 (10-8) 2-6 7-6 (9-7) and will now play Alicia Molik in the next round.

Australian Open losing finalist and former world number one Justine Henin was knocked out in the second round by Gisela Dulko 6-2 1-6 6-4, with her elimination meaning the likes of Caroline Wozniacki, who is through after beating Vania King, and Kim Clijsters (Wozniacki 14/1, Clijsters 7/2 to win on tournament outright coupon) must fancy their chances of winning the BNP Paribas Open.

World number 65 Baltacha said it was an “unbelievable feeling” to have recorded the biggest win of her career.

“I was stunned on match point. I think it kind of took me like 10 seconds to actually realise that she hit that backhand wide,” she stated.

Fourth seed Elena Dementieva and tenth seed Maria Sharapova are both into the third round after beating Olga Govortsova and Vera Dushevina respectively (Dementieva 5/1, Sharapova 8/1 to win trophy on outright coupon) .
