Pinchbeck, who has played No. 2 and No. 3 seed singles for North Carolina this season, will usually be in the midst of a third set or a tie-breaker.
You'll notice her talking to herself in her Australian accent, urging herself to play better, smarter and harder. You'll hear her teammates chant, "Rudy! Rudy!" from the sidelines, likening her to the main character of her favorite movie.
Most often you'll hear someone in the stands yell, "So tough, Kate. You're so tough."
That's what most people say about the sophomore from Edmonston Park, Australia.
"Kate has always had a reputation of being mentally tough," North Carolina women's tennis coach Roland Thornqvist said. "She's a team player, and she possesses all those qualities other than being a good striker of the ball, and that's one of the reasons we're so happy to have her on our team."
Thornqvist recruited Pinchbeck while she was playing at Mount Carmel Catholic in Varroville, Australia.
Pinchbeck, who is ranked No. 75 in the Intercollegiate Tennis Association rankings, said she was considering coming overseas to play college tennis when Thornqvist invited her to UNC.
"If I would have went to school at home, I would have had to stop playing tennis," said Pinchbeck, because there's no college tennis in her home country.
So she visited and fell in love with UNC and the closeness of the team.
