I just checked Addidas USTA COLLEGIATE INVITE(PORTLAND) site, and
USTA Player Development:
Coaches: Marc Lucero, Freddy Rodriguez
Gabby Andrews (Pomona, California) - High School Sophomore
Brooke Austin (Indianapolis, Indiana) - High School Junior
Jenny Brady (Boca Raton, Florida) - High School Senior
Caroline Doyle (San Francisco, California) - High School
Senior
Jessica Ho (Wexford, Pennsylvania) - High School Sophomore
Dasha Ivanova (Beaverton, Oregon) - High School Sophomore
Claire Liu (Thousand Oaks, California) - 7th Grader
Kimberly Yee (Las Vegas, Nevada) - High school Sophomore
Indeed, Caroline IS Senior, TRN got it wrong, so she's not graduating early or something.
