Williams walked off Arthur Ashe Stadium court with a wave and twirl then waited to find out who she will play in Saturday’s final, Reuters reported.
That was also decided quickly as Japan’s Naomi Osaka dismissed last year’s losing finalist American Madison Keys 6-2, 6-4.
Asked if she had message for Williams, Osaka, who beat Williams in their only head-to-head meeting, smiled and said, “Serena I love you.”
Just seven months and seven tournaments removed from returning to competition following the birth of her first child, Williams was back at her ruthless best and needed just 66 minutes to beat the 19th seeded Latvian and reach her 31st Grand Slam final.
A win on Saturday would also give the 36-year-old American a seventh US Open title, breaking a tie with Chris Evert for the most in the Open era.
Honestly, it is remarkable. I couldn’t have predicted this at all,” said Williams. “I got a little emotional out there because last year I was literally fighting for my life in the hospital.
“I was on my third surgery. I had one more to go still.
“To come from that, in the hospital bed, not being able to move and walk and do anything, now only a year later I’m actually in these finals, in two in a row.
“Like I said, this is the beginning. I’m not there yet. I’m on the climb still.”
It will be the second consecutive Grand Slam final for Williams who came agonizingly close to matching Margaret Court’s record of 24 majors at Wimbledon but was beaten by Angelique Kerber.
Despite her dominant display Williams estimated she is still only operating at 50-60 percent and then fired an ominous warning to her fellow players.
“There’s still much more that I plan on doing,” declared Williams. “I just feel like there’s a lot of growth to still go in my game.
“Even though I’m not a spring chicken I still have a very, very bright future.”
The 20-year-old Osaka, who is the first Japanese woman to reach a singles final of a Grand Slam, had to fight harder than the score suggested to get past 14th seed Keys, who paid the price for a lack of killer instinct.
The American carved out 13 break point opportunities, but Osaka saved all of them and was far more clinical herself, converting three of the four chances that came her way.
“This is going to sound really bad, but I was just thinking I really want to play Serena,” Osaka said in an on-court interview.
“It feels a little bit surreal,” she added to reporters. “Even when I was a little kid, I always dreamed that I would play Serena in a final of a Grand Slam.
“At the same time I feel like even though I should enjoy this moment, I should still think of it as another match. I shouldn’t really think of her as my idol. I should just try to play her as an opponent.”
Osaka won her first career title at Indian Wells this year but had never beaten Keys before in three attempts and lost to the American at Flushing Meadows in 2016.
“It still feels really weird because I’ve never beaten Madison before,” Osaka said. “She’s a really good player... I thought I was visibly shaking and stuff (from nervousness).”
