She might be at a US college, but she isn't playing. I'm almost certain she accepted prize money in her career and that makes her ineligible to play college tennis in the US. Anyways, she won her first match 6-0,6-2!
How do you mean? She beat 13th seed in QR3 6-2 6-1. One more Q round left.
Since she played pros and was high in the rankings, a team can say she accepted prize money (making her a pro. you can't be a pro and play college tennis). In her division, once someone challenges it, you have to sit out until it's figured out.
