South Korean golfer Grace Park is at the top of the leader board after three rounds at the Wachovia LPGA Classic Saturday.

At the third round held at Berkleigh Country Club, In Kutztown, Pennsylvania, Park shot a 7-under-par 65 for a three round total of 17-under 199 to take a one-stroke lead over American Jill McGill.

Players used umbrellas and ice wrapped in towels to combat the scorching heat of 89-degrees Fahrenheit, which some players called "the biggest challenge of the day."

The final round is set for Sunday morning, local time.

Park, the tournament's 2002 winner, will be aiming for her second victory of the season.
