America junior golfer Andrea Lee leads the women's division, but the United States sits two strokes behind Colombia overall heading into the final round of the Pan American Games.
Lee, the No. 2 player in the Golfweek/Sagarin Junior Rankings and a class-of-2016 Stanford commit, shot a 70 at Angus Glen Golf Club in Markham, Ontario, moving to 9 under overall.
At the event, which acts as a precursor to the 2016 Olympic games, there is a men's, women's and mixed team competition. The men and women compete for 72 holes, with the low men's and women's score being taken for each country to calculate the mixed team score.
