Huixquilucan, Mexico (AHN) - Stacy Prammanasudh is within one stroke of tying leader Meaghan Francella after shooting a 2-under 70 in the second round of the MasterCard Classic on Sunday.

Prammanasudh played 16 holes despite heavy rains, which ultimately delayed the second round of action.

Francella didn't play Sunday, but had a second straight 68 on Saturday, proving to be just enough to maintain the lead heading into Monday's final round of play.

"I'm still working on things. My swing doesn't feel completely perfect. I guess it never does," Prammanasudh told AP. "I'm just pleased to have played well today and hit some good shots to get some birdies out there."

South Korea's Seon-Hwa Lee finished 6 under, and two-time defending champion Annika Sorenstam is 5 under along with Karin Sjodin and Becky Morgan.

"I'm very happy where my game is," Sorenstam said during her first start of the young LPGA season. "When you get away from competition it's a little different. ... I try not to think too much about other things. I just have to focus on my game and hit one shot at a time."

Reigning LPGA Rookie of the Year Lorena Ochoa and Giulia Sergas are 4 under.
