Well done, Kei!
Nice to see a match like this for a change when he's not a slow starter.
Started really well in the first set despite the windy condition. In the second set, Robert hit back and showed why he was able to beat Berdych from two sets down at RG, he was up a break in the set before Kei leveled to 5-5. Kei did really well to take that close set and ran away in the third.
Good luck vs Souza or Ebden!
