"Yay, I made it to the end". It was certainly her best performance of a tournament that has found her scraping past the unheralded Aliaksandra Sasnovich in her first match, and then standing two points from defeat against Simona Halep on Wednesday.
While both the Williams siblings seem to have plugged the wormhole of time - Venus more so than Serena this year, so far - the elder Williams hasn't remained impervious to the passage of age.

The win means Federer has now only lost one match in the whole of 2017, when he surprisingly fell defeat to Evgeny Donskoy at the Dubai Tennis Championships at the second round stage.
Federer conceded that he has ridden his luck at times to advance.
"I would love it", Federer said. I feel very fortunate I was able to take advantage of a couple more opportunities than maybe her.
Garcia expecting tough Arsenal and Chelsea tests
Arsenal welcome Manchester City to The Emirates on Sunday afternoon one of the standout fixtures of the Premier League weekend. The flip-side of that argument is that having so many games against direct rivals gives you a real chance if you can win them.
"She finished previous year extremely well and kind of showed that she had the potential to get there with the wins that she was having", Murray said. The Spaniard came through a tough win over Acapulco champion Sam Querrey, 3-6, 6-2, 6-3, after nearly two hours.
"If the match would've gone three sets of tiebreakers or something even closer, it would've been really epic" said Federer. At the US Open that same year, it was 2-1 to Federer before del Potro grabbed the fourth-set tie-break and ran to his first-and only-Grand Slam title, 6-4. "I was more the aggressor. Having two or three set points in that first set and ending up losing it is kind of depressing, but I got a good start to the second set and that got me fired up and I just kept playing". A backhand fired long, and he faced his only break point of the set. He then erased a 15-40 hole to secure the first set. "I don't know what I was thinking", Kyrgios said.
Williams fought back strongly in the second set, breaking to go up 3-1.
Kyrgios defeated 16th-seeded Alexander Zverev 6-4, 6-7 (9), 6-3 in the last of the men's quarters, a match that lasted 2 1/2 hours.
On the other hand, Del Potro has not had much success this season and has slipped to top-ranked players of the likes of Milos Raonic (Delray Beach semi-final) and Novak Djokovic (Indian Wells second-round).
Stan Wawrinka, seeded No. 1 in an ATP Masters 1000 tournament for the first time, easily won his opening match against Horacio Zeballos, 6-3, 6-4.
