The ruthless performance from Williams set up a semi final match up with fifth seed Ukrainian Elina Svitoliona who is yet to drop a set this tournament.
She is now just one match win behind Chris Evert's record of 101 wins, and is 100-12 all-time in the tournament. It is really unbelievable.
The 37-year-old American broke serve five times and hit 25 winners as she eased to a 6-1 6-0 win over the 18th seed. I never thought I would get to 100 wins and still be here but I love what I do.
She said about her upcoming competitor: "She's had a great year", said Williams.
"Physically I'm feeling great and more importantly I'm having fun every time I come out here".
Williams will be the heavy favourite but Svitolina insists she expects the task of making the final to be just as hard if it is Wang who prevails.
"That's a good stat for me". Just too much for me, ' she mentioned.
Williams is also the last American - woman or man - standing in Flushing Meadows in hopes of taking home the fourth and final Grand Slam title of the season. "He's very different after (he plays) matches", Svitolina said on ESPN's broadcast.
Wang was able to get on the board but Williams wrapped up the first with a thunderous ace, and kept her foot firmly on the gas in a second that somehow managed to be even more one-sided.
"I can not handle it". Svitolina eliminated 16th-seeded Johanna Konta of Britain 6-4, 6-4 earlier Tuesday.
Serena Williams on Tuesday tallied her 100th main draw win at the US Open. She uses flat shots to place the ball wherever her opponent isn't, and that works well against players who take a lot of risks. Obviously, Serena is an fantastic champion. "It is probably going to be really tough against her".
This was the third straight year that Federer lost at the U.S. Open when he seemed to be playing at top form. It's a grand slam.
"I knew I needed to come out tonight and play well".
"It's the best I have ever done so far in my career". She had a lot of treatment, and she's fine. The loss kept Konta from becoming the first British woman to reach the semifinals of all four Grand Slams in the Open Era. Belinda Bencic meets Donna Vekic and then at night Bianca Andreescu battles Elise Mertens.
