Mary Stoiana vs Tereza Valentova — R128 — Cincinnati Open

Return pressure arrived in volume rather than in accuracy. Valentova built 12 break points to Stoiana's four and converted five of them, backed by 77% of first-serve points won against the qualifier's 58%. Two of those breaks landed early in the second, for 2-1 and then 4-1, before Stoiana broke back in game 10 for 5-5 and saved a match point along the way. The Czech settled it in the tiebreak, 90 minutes in, ending a three-match losing run.
