#FunSizeOnTheRise still applies at the US Open, where 5'5" world No. 141 Kristie Ahn is into the final 16, with a 6-3, 7-5 win over Jelena Ostapenko on Grandstand on Saturday. Her match point was sealed with an ace.
"It was exciting, because I hit an ace, which I never do," Ahn said. "I could finally let my emotions get to me. The crowd roared. It was such a cool environment. Yeah, when I looked back, I was like, You cried, what a little baby. All my friends told me they cried, too, so I guess that's okay."
The WTA doesn't even list her height; the 5'5" is according to Stanford, where she was on the 2013 NCAA Championship–winning team.
