Konta, who won her first WTA title at this event back in 2016, did not let her fans down after handing 23-time Grand Slam champion Williams the most lopsided defeat of her career ― 6-1, 6-0.
The tournament lost another big name when top-seeded Spaniard Garbiñe Muguruza pulled out of the tournament with a right arm injury, hours before she was to face former world number one Victoria Azarenka for a place in the quarters.
“I’ve been feeling some pain in my right arm for a couple of days and realised I am not ready to play the match, so hopefully I can recover for the next tournaments,” Muguruza said in a statement.
For Konta, however, it was full speed ahead.
The Briton needed just 70 minutes to dispatch Kenin, blasting 20 winners including nine aces, with just 13 unforced errors.
Kenin put up a determined defense, but 19 unforced errors proved too much to overcome and she was unable to convert either of her two break point opportunities.
Konta, a former world number four now ranked 48th, next faces fourth-seeded Elise Mertens of Belgium for a place in the semi-finals.
Mertens reached the last eight with a 6-2, 6-0 victory over American wild card Ashley Kratzer.
In other early second-round action yesterday, American Danielle Collins defeated Vera Lapko of Belarus 6-1, 3-6, 6-1.
Collins next faces either Azarenka or Russian Anna Blinkova, the lucky loser drafted to replace Muguruza in the draw.
