ATLANTIC CITY, N.J. -- For the second straight day, first-year Michelle Piyapattra carded the low round of any individual in the tournament -- a one-over par round of 73 -- and leads the 2011 Ivy League Women's Golf Championship by six strokes heading into the final round on Sunday. Piyapattra tallied two birdies on the front nine and had a string of seven straight pars to close out her round.

After birdieing the first hole on Friday, Piyapattra three-putted for bogey on her opening hole of the day before rebounding to shoot two-under over the final eight holes of the front nine to make the turn at 36 (-1).

The only blemish on the Corona, Calif. native's scorecard on the back nine came on the par-4 11th, where she took a double-bogey. Piyapattra weathered another tough day of conditions out on the golf course and had birdie putts on five of the final seven holes, settling for par on each of them.

The first-year will begin the final round of the tournament on Sunday six strokes ahead of both Mia Kabasakalis of Harvard and Rui Li of Penn. Kelly Shon of Princeton tied Piyapattra for low round of the day and is tied for sixth overall.

As a team, the Lions stand in fifth place at 643. First-year Jane Dong also had a strong day on the links, shaving six strokes off her first-round score to card a 78. Junior Robin Lee birdied the par-5 13th and shot 83 for the day, and stands in 28th position individually.

Sophomore Ashley Zambito finished her second 18 holes of the tournament with an 88, while junior Lynda Kwon rounded out the Columbia competitors at 90.

Penn and Yale are tied atop the team standings at 620, with the Quakers firing the low round of the day of 306.

The third and final round of the Ivy League Championship will take place on Sunday, April 24, beginning at 7:30 a.m.
