WASHINGTON — Emma Raducanu dominated her first career matchup against Naomi Osaka, winning the showdown at the D.C. Open on Thursday between past US Open champions 6-4, 6-2.
Raducanu, the only qualifier to claim a Grand Slam title when she did that in New York in 2021, saved the only two break points she faced and managed to break the big-serving Osaka three times.
Osaka was hurt by seven double-faults. She has won the US Open and Australian Open twice each.
Raducanu, who is ranked 46th, will face Maria Sakkari in the quarterfinals. Sakkari eliminated No. 2 seed Emma Navarro on Wednesday.
Venus Williams, the seven-time Grand Slam singles champion back on tour at age 45, was scheduled to face Magdalena Frech at night.
Winners in men’s action Thursday at the hard-court tournament in Washington included No. 8 seed Daniil Medvedev and No. 14 seed Brandon Nakashima.
