She defeated tennis newbie and French Open champion Jelena Ostapenko in the quarters and bruised past Johanna Konta to inch closer to Serena's record. While Venus is nearing her potential eighth Grand Slam title, Serena won't speculate on her chances.
With her sister out on maternity leave, Venus Williams has ensured that the Williams name could still be in the history books after Serena's two-year dominance.
She has had the tougher path to reach the final, including defeating world No 1 Angelique Kerber in three tight sets and former two-time Grand Slam champion Svetlana Kuznetsova, but is into her second Wimbledon final.
Fortunately for Muguruza, she isn't still running around looking for a Grand Slam title in her third final.
Spain's Garbine Muguruza (L) and United States player Venus Williams pose with their trophies after Muguruza won the women's singles final on the twelfth day of the 2017 Wimbledon Championships at The All England Lawn Tennis Club in Wimbledon, southwest London, on July 15, 2017.
Williams, a five-time champion who had been trying to become the oldest victor of a major in the Open era, had squandered two set points at 5-4 in the first set.
The two women will take to center court on Saturday, with the final due to start at 9 a.m. ET (2 p.m. local time). She then beat the American in the French Open final last season.
Venus, aged 37 and undergoing a barely credible tennis renaissance, last stepped out onto Centre Court to contest a singles final in 2009.

"There's definitely a lot of ups and downs, and I just try to hold my head up high. But I just liked how big he played". She needs more shape on the ball and I actually found myself nervous every time I was watching in the Venus match because it was too high over the net.
"Definitely I want to win, for sure", Muguruza said on Friday. "We work so many years for these moments that she has right now, and I'm really happy for her", the 23-time Grand Slam victor told Yahoo Sports.
At 37, Williams was bidding for her sixth championship at the grass-court major, 17 years after her first. I don't think I could ever be that nervous.
Federer still has not dropped a set but was tested by Berdych and the match might have panned out very differently had just a few points gone the Czech's way. And I'll have time, it will be fun. "And usually it's her in these finals, so I'm trying my best to represent "Williams" as best as I can".
As well as inspiring the next crop of aspiring young players, Konta caught the imagination of the British public with her pulsating victories and courageous style of play.
