Excellent way for John to get his first win at a major.
John was really shaky in the first two sets but he picked up his game in a big way for the last two, even winning some rallies and cleaning up on his volleys.
34 aces from John and averaged 129 on his first serve and 115 on the second, maxed out at 143. John converted on his first break point opportunity and saved all 7 that he faced. He also had 2 MPs at *3-5 on Jarkko's serve (1/3 on BPs for the match).
Rik de Voest is next.
