Japan Open: Mochizuki moves into quarter-finals, shocks top seed Fritz

Japanese wildcard Shintaro Mochizuki advanced to the last eight of the Japan Open by edging out American Taylor Fritz, the top seed, 0-6, 6-4, 7-6 (2) at the Ariake Colosseum in Tokyo on Thursday.

Mochizuki is the only Japanese man left in the field, and this was his first-ever top 10 win – indeed, only the second ATP Tour win of his career.

Mochizuki, ranked No 215, will play Australian Alexei Popyrin next.

Ahead of his victory, the 20-year-old Japanese beat Argentinian Tomas Martin Etcheverry (6-4, 7-6 (5)).

Fritz, ranked No 10, won against Cameron Norrie (6-4, 6-3) in the previous round of the Tokyo Open.
