Venus Williams, who turned 37 last month, needed just over an hour to get past 19-year-old Ana Konjuh 6-3, 6-2 at Wimbledon on Monday. Ostapenko finished with 42 winners in the match. But she looked fighting fit, in mind and body, and all at once, was also in contention. Querrey also reached the last eight a year ago after his upset victory over Novak Djokovic.
In the opening seven days of play, 14 matches on Centre Court have been from the men's singles draw while only eight have come from the women's.
The former Wimbledon champion said that she is happy for the young Latvian.
She soon proved these were no empty words. It's just been such an wonderful result for her.
Williams capitalised to take the first set in less than 30 minutes and move one step closer to the next round.
"When I was a little girl, and even now, I dreamed of being in these battles and on the big stages", Konta told BBC Sport after her victory.
Ostapenko was leading 5-2 in the second round, but she has been the victim of a breach, and caused the tie-breaker. As a result of her dominant win on Monday, she hit seven aces in addition to winning 31-of-36 first-serve points. She held and broke, and now it was her turn to serve for the set.
The nature of her game, all-out attack, was reflected in the stats: 42 winners to 39 errors.
The fivefold champion of Wimbledon, Venus Williams, has triumphed, while the favourite, Angelique Kerber has bent the spine. Then she was roundly outhit by Ostapenko in the final. "You know, so I'm definitely really happy for her". "I would say it's taking the marquee matches", All England Club chief executive Lewis said. Typically, the American fought off a smile midway through the second set when her screaming forehand victor was met with a "I love you, Venus" shout from the crowd. "Honestly, I don't remember". I will have to observe the nuances at the beginning of the meeting, because it is very hard to predict what will happen.
In this series, this is the fourth round match for both the players.
Kerber had to reach the final here, as she did previous year, to have any chance of retaining her place.
