Result

Qualifier Shintaro Mochizuki upset Ethan Quinn 6-2 7-6(6) 7-5 in a 2h 36m grass-court test on Court 14. The Japanese made the most of his return, converting 5 of 11 break points to Quinn's 2 of 13 and out-hitting the American 39 winners to 30. Quinn served the bigger ball — 12 aces to 6 — but also coughed up seven double faults and could not shake Mochizuki, who saved off the pressure in a tight second-set tiebreak and closed from 5-all in the third. Mochizuki won 126 points to 101 to reach the third round in their first meeting.

At this Stage

Ethan Quinn arrived with the bigger billing — the higher ranking, and a first-round statement over No. 14 seed Luciano Darderi, 7-6(7) 7-5 6-2. Shintaro Mochizuki arrived from qualifying, having conceded all of three games to fellow qualifier Max Basing (6-3 6-0 6-0). The qualifier kept right on rolling, 6-2 7-6(6) 7-5 in their first meeting; Quinn, for all the bigger serve, exits with the reminder that billing wins nothing here. Mochizuki takes his place in the last 32, where No. 23 seed Rafael Jódar waits — and qualifying already feels like a long time ago.
