The British No.1 advanced after one hour and nine minutes on Centre Court, joining countrywoman Harriet Dart to make two British women in the third round for the second time in three years.

"I definitely felt like I served well today," she said in her post-match press conference. "I felt like I actually served quite well in my first match, as well. I think on a surface like grass, that definitely can always help.

"I was just pleased I was able to ask her enough questions and keep things moving for her not to be able to get a real grip on the match, and I just was pleased I was able to come through."

Seeded No.19, Konta has been in the midst of another career surge since the start of the clay court season, reaching two finals at the Grand Prix de SAR La Princesse Lalla Meryem and the Internazionali BNL d'Italia before making her third career major semifinal, this time at Roland Garros.

"I don't really compare myself to myself. I think I'm in a good place right now. I think I'm playing good tennis. I'm definitely enjoying the tennis I'm playing. I feel like I'm asking my opponents a lot of questions. I feel like I'm answering quite a few, as well, when they ask me questions out on court.

"I think I've been kind of building on my level each tournament, each match I've been playing as the season has been going. I'm pleased with that. We know it's never just an upward trajectory."

Taking that renewed confidence to her home Grand Slam tournament, the former World No.4 defeated Ana Bogdan in the first round and enjoyed an even quicker start against Siniakova, a top-ranked doubles star who won the women's doubles title at SW19 last year with Barbora Krejcikova.

"Don't get me wrong; I get nervous and excited whenever I play on Centre Court, but overall, I just look forward to every opportunity I get to play at the Championships. I never take it for granted, and I'm just really pleased to give the best performance I could for the people that came to watch. I'm really happy that I get to play another match here."

Siniakova shook off a scary spill early in the match but Konta's momentum was unmoveable as she secured the only break of the opening set and held on without facing a break point.

The second set saw more routine service holds before the 2017 semifinalist carved out a 15-40 lead in the seventh game, converting her third break point and held serve twice more to secure victory.

In all, it was a clean match from Konta, who struck 23 winners to 20 unforced errors and didn't face a break point the entire match as she maintained a 76% on her first serve, winning 79% of those points.

Up next for the Brit is a rematch of her Roland Garros quarterfinal clash with 2017 US Open champion Sloane Stephens, who breezed past Wang Yafan to kick off Day 4 at the All England Club.

"She's an incredibly good player. I think for me to have won our three encounters so far, there's very little in that, because every time we step out onto the court, it's 50/50.

"I think more than anything, I'm looking forward to playing her again. I like playing really great players. I like playing big matches like that. Just looking forward to sharing the court with her again. It is a nice change playing her on the grass this time. We're kind of going through all the surfaces, which is fine."

Konta has won all three of their matches in 2019 - dropping just one set in Rome - though this will be their first meeting on grass.

"I think records don't necessarily mean a lot when you step out onto the court at the beginning of the match. I think Sloane is one of the best players in the world. She's a Grand Slam champion, another Grand Slam finalist."
