Bencic has been a nightmare opponent for Osaka in 2019, bagging her third win over the defending champion, per sportswriter Ben Rothenberg:

Belinda Bencic notches her third win over Naomi Osaka this year, beating the defending #USOpen champ and #1 seed 7-5, 6-4 to reach her first Slam QF in five years. Not a bad match by Osaka, who finished with a +5 winners/unforced differential, but Bencic (at +17) just too good.

It marks the 22-year-old's second trip to the U.S. Open quarter-finals, five years after her first.

Bencic has been steadily building up her form this year, using her excellent ability to counter in rallies to great effect. Her playing style makes her a nightmare opponent for Osaka, who likes to use her power from the baseline to win points.

Their clashing style of play made for some great highlights:

With 29 winners and just 12 unforced errors, Bencic picked a great time to play some of her best tennis, and she will be a handful moving forward. She'll face Vekic in the next round, after she came from behind to beat Goerges.

In the men's draw, Schwartzman overcame struggles in the first set to beat Zverev, taking full advantage of his many mistakes on serve.

The German hit an incredible 17 double-faults, part of what was a dreadful day for the talent, per sportswriter Uche Amako:

17 double faults, 65 unforced errors, just 33% of points won on second serve equals a horrible day for Alexander Zverev. His career is in freefall at the moment. Credit to Diego Schwartzman, who has played some stunning tennis today #USOpen

The 22-year-old still hasn't made it past the fourth round of a Grand Slam outside of the French Open. Schwartzman will face Rafael Nadal or Marin Cilic in the quarter-finals.
