The April update of the Players To Watch 2013 Girls Top 100 National Ranking is primarily affected by recent goings on at the youth national team level, as callups and performances at a trio of camps held last month at Home Depot Center made their mark on the lists.

Strong performances with the U17 WNT kept standouts Joanna Boyles and Morgan Andrews 1-2 on the list, while Michigan Hawks forward Summer Green moves to #3 just ahead of Colorado Rush midfielder sensation Gabrielle Miranda. Colorado Rush midfielder Morgan Stanton is the only newcomer on the list this month, while Michigan Hawks’ Rilka Noel, fresh off a great week with the U15 GNT, is the month’s biggest mover.

The 411: TopDrawerSoccer.com's Players To Watch rankings utilize national rankings out of a 16-region setup.  Every Monday we will feature a national top 100 update for one of four rankings (2012 and 2013 Boys and Girls), while Tuesday through Friday we will update one of these regions for each feature. This way every regional and national list is updated once per month.

Players To Watch Regional Rankings and National Top 100 in 12 age groups are based on staff assimilation of data and feedback received from coaches and other observers around the country.

For the uninitiated, our 16 regions are Southern California, Northern California & Hawaii, the Pacific Northwest (AK, WA, OR, ID), Rocky Mountains & Southwest (MT, WY, CC, NM, AZ, NV UT), Texas, Heartland (KS, MO, IA, NE and the Dakotas), Midwest (IL, WI and MN), Great Lakes (OH, MI, IN, KY), South (MS, LA, AK, AL, TN, OK), Florida, South Atlantic (SC, NC, GA), Mid-Atlantic (DE, VA, MD, WV), Pennsylvania, New Jersey, New York, Northeast (MA, CT, RI, VT, NH, ME).
