Upon further research by statistics guru extraordinaire Peter Hirdt of Elias Sports Bureau, we have discovered that Christine Nairn is the 9th youngest player ever to score a goal for the full U.S. Women's National Team. Kristine Lilly was the youngest at 16 years, 22 days, a record that will likely never be broken (one of many seeingingly unbreakable records by Lilly!).
