Nishioka was amazing in his last two matches and he defeated Rio Noguchi with 6-3 6-2 and Aleksandar Vukic with 6-3 6-3 and i think that he can win with under 21.5 games here against Shevchenko, Shevchenko lost his last match with 6-3 6-1 and he plays his best tennis on clay ,on the hard courts he is much weaker.
