A resilient Pegula, the world No 5 from the United States, eventually progressed just a day after laboring more than three hours to beat 72nd-ranked Yulia Putintseva of Kazakhstan.
The latest hard-fought win, clocking in at just over two hours, was revenge for Pegula, who was stunned by Cocciaretto at Wimbledon last year.
Cocciaretto, ranked 43rd in the world, dominated the first set.
Pegula's serve was notably wayward, with the American winning just 25 per cent of first serve points.
"I don't know what I was doing out there... Oh my gosh, that's horrible," said Pegula after.
Jpeg stepping up 😤

Pegula rallied in the second set, but was immediately broken in a topsy-turvy final set, in which she trailed 1-4.
The American hauled it back to 4-4, but then found the net on a break point that would have given her the lead.
Two points from defeat at 4-5, Pegula fought back to 5-5 and they advanced into a deciding tiebreak.
Pegula drew first blood, going up 1-0 off Cocciaretto's serve, then won every point on her own serve before Cocciaretto double-faulted to hand her the match.
"She beat me the last time we played, so there was a bit of a mental thing too, but I was able to serve really well, I think, at the end," Pegula said. "And then I just held my nerve."
Pegula, who won the title in Dubai in February, next faces Russia's Diana Shnaider – a 6-3, 6-0 winner over Canadian Leylah Fernandez.
Swiss third seed Belinda Bencic also advanced, shrugging off a slow start to beat Czech Sara Bejlek 7-6 (7/4), 6-2 and line up a quarterfinal clash with fifth-seeded American Madison Keys.
Keys beat Hungarian Anna Bondar 6-2, 7-5.
