I see 6-0 on ITA. It's supposed to be 6-1. Diaz conceded the match. Ansari wanted to keep playing, Brasseaux wanted to keep playing. Both players were shocked when they called it. Even the remaining UGA fans booed a bit because they wanted to see more tennis.
I looked at Ansari's personal results and it even has him listen as losing the first set 4-6. Just typical college tennis stat incompetence.
