Venus added another chapter of achievement to her professional history as she became the oldest Wimbledon semi-finalist for 23 years after sweeping aside French Open winner Jelena Ostapenko on Tuesday.
There was more appreciation from the crowd when Rybarikova held on in a long service game to get on the scoreboard for just a second time, but Muruguza was in ruthless mood and confidently served out the match.
One name on the board who has been an inspiration is Conchita Martinez, Spain's Fed Cup and Davis Cup captain who is with Muguruza at Wimbledon in the absence of her regular coach, Sam Sumyk. She must be considered the favorite in their meeting due to her experience.
The British number one had two break points at the end of the opening set but failed to capitalise and instead it was Williams who broke the very next game.
Deliberately taking her time between points and games, Venus was doing her best to throw Konta out of her rhythm.
It will be the second trip to the Wimbledon final for Muguruza, who advanced by beating unseeded Slovak Magdalena Rybarikova 6-1, 6-1. She has won five singles titles and six doubles titles, all with her sister Serena. It is five since she lost in straight sets in the first round to Elena Vesnina. "It's going to be, you know, like a historic final again". Konta actually led their head-to-heads 3-2, including a victory over Williams at the tournament closest to her home, the Miami Open, in March. Williams in stark contrast settled quickly on her 21st outing in the last four of a major and after dismissing an early scare never looked back in pursuit of a berth in the final. Her most recent came in 2008, when she defeated her younger sister, Serena, for the title.
"I think I played very well, for sure", said the Spaniard.
Garbiñe Muguruza, the Spanish No 14 seed, just spiked another big gun.
This is Williams's 20th year at Wimbledon. But I think I've also got to acknowledge the level of how my opponent played today.
"I think a lot of things are clicking also with her and the team this week, so it's very nice". "But complete focus and a great game plan from Muguruza". "I thought the difference would be return of serve and that's what did it". You know, I was showing more emotions on the court. That would crazy for me.
