Adolfo Daniel Vallejo def. Valentin Vacherot 6-3, 6-3 — Cincinnati Open 2026 R64

Match recap

Adolfo Daniel Vallejo defeated Valentin Vacherot 6-3, 6-3 in the R64 of the Cincinnati Open 2026.

Fourteen aces bought Vacherot nothing. The 15th seed, a 63 percent favorite with the betting market, never carved out a single break point and dropped all nine of his return games. Vallejo answered with two aces of his own, held every service game, and converted all three break chances he saw — the first in game 5 for 3-2 — while keeping his unforced errors to 13 against the seed's 28. Eighty minutes of return pressure leave the Paraguayan with the highest-ranked win on his record, one rung above No. 21 Learner Tien, beaten in Madrid in April, and a place in the last 32 at Cincinnati.
