Since returning to action after the birth of her first child Williams has come agonisingly close to matching Margaret Court's mark three times and will have a chance on Saturday to do so in front of an adoring home crowd for a second successive year.
Last year Williams was left in tears following a chaotic and controversial loss to Naomi Osaka on Arthur Ashe Stadium. She has also lost two Wimbledon finals since her return.
Now all that stands between the 37-year-old and her Holy Grail is Canadian Bianca Andreescu or Swiss Belinda Bencic, who will meet in the other semi-final later on Thursday.
The semi-final offered a classic match-up of styles with Williams and her prodigious power up against Svitolina, one of the best counter punchers in the women's game.
Williams did not have her 'A' game in warm conditions but the former-world number one knew exactly what was needed particularly on the big points.
The fifth seeded Ukrainian had no shortage of chances but could not convert any of six break opportunities.
A ruthless Williams, however, bombarded Svitolina with punishing forehands and six aces to register her 101st US Open win, which tied her with Chris Evert for the most at Flushing Meadows. Williams arrived at the year's final Grand Slam with a scowl and an all business demeanor that has left a path of devastation.
Any concerns over the back spasms that forced her to quit the Toronto final and out of Cincinnati were eased when Williams opened her Flushing Meadows account with a 6-1 6-1 demolition of old rival Maria Sharapova.
That was followed by routine wins over Karolina Muchova, Petra Martic and Cat McNally before blasting her way into the last four with a jaw-dropping 44-minute 6-1 6-0 rout of China's Wang Qiang. But as cold-blooded as those performances were, Williams' 70-minute dismantling of Svitolina in front of an approving packed house said more by delivering an emphatic message she will not be leaving Flushing Meadows without a share of Court's record.
The match had looked to be a long and competitive affair when Svitolina forced Williams to fight off three break points to hold her opening serve.
Williams, however, was ready for the challenge breaking Svitolina at the first opportunity by firing a winner down the line the Ukrainian could only look at.
That was the only break of a grinding first set but all Williams would need for a 1-0 lead.
It was not a good omen for Svitolina with Williams holding a 94-1 record when winning the first set at the US Open.
Svitolina would hold serve to open the second but Williams then swept through the next six games to advance to her 33rd Grand Slam final.
