In her seven victorious finals at The Championships, she has dropped just two sets: to Venus Williams in 2003 and to Agnieszka Radwanska in 2012.
Following the announcement Williams said: "We've always had a wonderful friendship".
Let others shrug at this latest accomplishment, as if all it signified were merely another chance at another in a long line of trophies. "She's a good grass-court player and is going really well" Williams added.
The former world number one developed a "slew of health complications" after developing a pulmonary embolism 24 hours after her baby's arrival.
Even after all of that, even after more than a year away from the game, even in only the fourth tournament of her comeback, Williams showed she's still capable of dominance.
Although Serena Williams seemingly restored a sense of normality by reaching the final at the All England Club for the 10th time in her illustrious career with a comfortable 6-3, 6-4 triumph over Julia Goerges on Thursday, this time her appearance in the showpiece is far from ordinary.
The 23-time slam champion will equal Margaret Court's all-time haul of major titles if she beats Kerber on Saturday.
After hitting five aces with a serve that reached 119 miles per hour, delivering 16 winners to only seven unforced errors, and covering the court so well with speed and effort against Goerges, Williams will face another German, 11th-seeded Angelique Kerber, on Saturday. Earlier on Centre Court, another German, Angelique Kerber, overcame Latvia's Jelena Ostapenko 6-3, 6-3. She is the second woman to accomplish this in the Open Era following Chris Evert, who played in a major final for 14 straight years between 1973 and 1986. That's wildly impressive. Believe me, I know she wants to go out there and win.
Kerber did not dictate much, content to let 2017 French Open champion Ostapenko determine the outcome of almost every point. Kerber, who lost to Williams in Wimbledon's 2016 final, will have a shot at redemption in what's already been a solid season. Williams won that one for a second consecutive title at the All England Club, before missing the grass-court tournament previous year while pregnant. Goerges, playing her first Slam semifinal, sent a forehand flying wide off the sidelines to concede serve.
