In just her second tournament following son Leo's birth, the 27-year-old Belarusian hopes to become the first mother to lift the Wimbledon women's singles trophy since Evonne Goolagong in 1980. I lost to her 7-6 in the third there so it was very close.
"I'm playing some good tennis but I don't think I'm playing unbelievable tennis", the Australian-born player said. I had to find my rhythm, and, you know, I never played her before. Konta's movement around the court is solid, and her serving got her out of trouble on more than one occasion on Wednesday, and so it might well come down to some of those free points.
Now she'll have this victory to cherish, along with another one from this year that also holds some significance: Brengle beat Serena Williams at a tuneup tournament at Auckland, New Zealand, back on January 4.
World No.1 Angelique Kerber and Spain's Garbine Muguruza, who both play third rounds today, are also gaining momentum.
There are two all British doubles matches scheduled for Thursday.
Eighteen-time Grand Slam victor Chris Evert and Britain's former Wimbledon semi-finalist Tim Henman have been among those to say they think Konta can come close to matching Wade's achievement.
Watson has dropped to a ranking of 102 after a hard start to the year, but an impressive grass-court season - which included a run to the Eastbourne semi-finals - will see her rise back into the top 100. "I don't anticipate anything different, other than a really, really tough battle for me". I know how well I can play. But mentally I'm really glad that it's over.
The temperature soared toward 85 degrees (near 30 Celsius) after being in the low 70s (20s Celsius) the prior two days. I could easily put myself in her shoes and feel what she was feeling.
But it felt as though the crowd wanted a battle, and the Italian provided it, winning the second set. "But a very slow animal".
Show it she did, displaying an enviable armoury. In the first and last sets combined, Kvitova made 45 unforced errors to 11 for Brengle.
Victoria Azarenka of Belarus is back in the third round as the two-time Wimbledon semifinalist ousted 15th-seeded Elena Vesnina of Russian Federation 6-3, 6-3 in one hour and 38 minutes.
But there was more drama to come when Watson, who had considered using up her last challenge earlier in the set before opting against it, correctly challenged a baseline call to bring up break point, which she duly dispatched to level again.
Former champions Rafael Nadal and Venus Williams continued to move through the draw, earning their places in the second week of the championships. "I don't think I'm playing unbelievable tennis", Konta said. However, I guess like with any tournament, the time I have to do stuff is quite limited anyway, so I am enjoying just staying at home, chilling out and making muffins.
