Naomi Osaka vs Anastasia Zakharova — Round of 128 — US Open. Osaka won 7-6, 7-6.

Serving for the match in game 10 of the second set, Osaka was broken back for 5-5, Zakharova saving a match point to force a tiebreak. The first-strike blueprint carried her out of it: nine of the 13th seed's 10 aces came in that second set, and she won 72 percent of first-serve points to the 101st-ranked Zakharova's 62. Everything else finished level — 12 games each, four of seven break points converted by both — which left the 90-77 count in total points as the only real separation. Two hours and one minute for a first-round win, and the two-time champion is through in her first match since Rybakina stopped her in the quarterfinals at the Canadian Open.
