Blake Mott (ATP820) comes out swinging freely against a poorly serving Nick Kyrgios (ATP178) and causes the upset of the day (or tournament) by taking out the seeded player, with a 63 75 win.
Is this the highest ranked player Mott has beaten to date?
Yes. The previous one was Brydan Klein (233) who was beaten at China futures in April.
Blake is 17yo only! I remember Sharapova chose him to practice with at AO in January
