Going into the match it seemed like an even match-up - Bouchard the No.1 seed and a semifinalist here last year, Davis one of the best counterpunchers in the game and feeling at home on clay.
But all of that went out the window once they took center court, as Davis became the aggressor - she hit a whopping 18 winners to just five, yes five, unforced errors in the match. Meanwhile, Bouchard's game went somewhat awry - she put together a -21 winners-to-unforced errors differential (12 to 33).
After running away with a 6-3, 6-1 victory, the soft-spoken Davis was interviewed on the court.
"I'd never beaten her before, so I came out knowing I had nothing to lose," she said.
"I knew to beat her I'd have to be fearless - I saw this as a great opportunity."
And on looking like such a natural on the clay? "I think clay really works for me, because I'm pretty fast," Davis said. "I can slide really well and I can make a lot of balls, so it really works for me."
Bouchard talked about the match a little later in her post-match press conference.
"I obviously hate losing but I'm not going to be too hard on myself," Bouchard commented. "I know I've not been feeling like myself on the court, so it's just a matter of taking some time now, not playing a tournament, and just taking some time to train and get back to feeling like myself on the court.
"I definitely felt a little bit slow today, overpowered, which is never usually the case. Usually I'm the one who's dominating. So it was definitely just not good - whatever happened was just not good."
Davis' win over the World No.7 was the second Top 10 win of her blossoming career. Her first Top 10 win came against a No.4-ranked Victoria Azarenka in the second round of Indian Wells a year ago.
Other winners as the day session wrapped up included No.4 seed Sara Errani, who battled over two hours to edge 2014 finalist Jana Cepelova, 6-3, 7-6(5), and No.15 seed Mona Barthel, who held off a late surge from Sloane Stephens, 6-3, 7-6(2) - she originally led 6-3, 5-3 with double match point.
