Angelique Kerber (33) has also won the generation duel with Cori Gauff and is in the quarter-finals of Wimbledon.
The 2018 tournament winner prevailed on the Center Court on Monday 6: 4, 6: 4 against the 17-year-old US young hope.
For Kerber, it is the first quarter-finals in a Grand Slam tournament since her Wimbledon victory three years ago.
As the only title holder remaining in the field on the “holy lawn”, Kerber will now face Australian Open semi-finalist Karolina Muchova (Czech Republic / No. 19) on Tuesday.
The Kiel woman, who was placed 25th and had already won the dress rehearsal in Bad Homburg, now has nine victories in a row on grass.
The game against Gauff, who was also strong recently and who is five places ahead of Kerber in the world rankings, was characterized by wind and some nervousness at the beginning.
The first five games all ended with service losses - but after the break to 3: 2, the Kiel woman no longer gave up the advantage and used the second set ball after 32 minutes.
After the difficult start, Kerber found her rhythm better and better.
The three-time Grand Slam winner often cleverly countered her 16-year-old opponent, the aggressive Gauff had to fight hard for every point.
The game picked up speed and class, but apparently the exhausting three-set matches in the run-up had also left their physical mark.
Kerber seemed to have slight problems with his thigh - the break to 2-1 due to a double fault by Gauffs was just right.
Kerber did not show himself to be much impaired and strongly opposed the brisk US “child prodigy”, already praised by many as the upcoming star of the scene.
Kerber fended off two breakballs at a possible 4: 4 with great nerves and also survived the last dicey situation.
Zverev fails on its own serve
The so far so strong serve once again caused enormous problems for Zverev in his match against Auger-Aliassime in number one after a long time. Zverev made eight double mistakes in the first set, which he gave up after a 4-2 lead. Something similar happened in the second set against the 20-year-old Auger-Aliassime, whom Zverev had defeated in the previous three comparisons. With a bit of luck, Auger-Aliassime fended off a set ball in the tie-break. Zverev dived the ball of the world number 19 in vain. after and a little later was behind with 0-2 sets.
In a 2-1 lead in the third set, Zverev slipped away when he wanted to run into a ball on the baseline. He remained lying down and grabbed his right knee, but was able to continue and actually saved himself in the fifth set, where the 18th double fault cost him a break. After a short rain break, the world number sixth struggled to prevent the 0: 3 under the roof and instead took a 3: 2 lead. But the consistency of the service was missing, after 4:01 hours Auger-Aliassime cheered.
