MIAMI, FL, USA – A former World No.21 and perennial doubles threat, Elena Vesnina needed to fight through qualifying just to reach the main draw of the Miami Open, but the veteran Russian caused one of the biggest shake-ups of the event thus far, outsteadying No.10 seed and former No.1 Venus Williams, 6-0, 6-7(5), 6-2.

“That was a great match, great fight,” she told Andrew Krasny during her on-court interview. “It’s always an honor to play against Venus. She’s a great champion. We played many times against each other and it’s always been a pleasure to play her and it’s always been a tough match-up.

“I’m really happy that I won today.”

Far from the typical underdog, Vesnina came into the match with a solid week at the Qatar Total Open – where she earned back-to-back wins over Simona Halep and Caroline Wozniacki and ended Martina Hingis and Sania Mirza’s 41-match winning streak in doubles – and an even head-to-head against the illustrious American. Landing 74% of her first serves to start, she took advantage of a flat opponent to race through the opening set without losing a game.

“I honestly was a little bit shocked after the first set, thinking, ‘Ok, what’s going on?'”

The second set was a more even affair; though Vesnina took what appeared to be a decisive break in the seventh game, Venus broke back at the eleventh hour, saving a match point on the Russian’s serve at 5-4.

“Even when I was up 5-3, I felt Venus was playing better and better and she raised her level up.”

Pushing the second set into a tie-break, the momentum swung back and forth before Venus swept the final two points, ensuring that the crowd would see a final set.

“She was serving incredibly; on the tie-break she played at a very high level of tennis.”

Undaunted – and perhaps aware that she won their only prior three-set match at the Western & Southern Open back in 2013 – Vesnina raced out to another 3-0 lead; though Venus pegged her back to within a game of level terms, the reigning Australian Open mixed doubles champion ultimately hit more winners (35 to 28) and fewer errors (35 to 39) to clinch the victory.

“Even though I lost the second set, I still believed in myself, and I knew everything could happen. It was a pleasure to play on this center court.”

Up next for Vesnina is No.24 seed and Australian Open semifinalist Johanna Konta, who defeated Danka Kovinic, 6-4, 6-2. With No.6 seed Carla Suárez Navarro out at the hands of American CoCo Vandeweghe, the highest seed left in this quarter of the draw is BNP Paribas Open champion Victoria Azarenka, who is ranked in the Top 10 but seeded No.13.

Vesnina is also in the doubles draw, set to play her first round with 18-year-old Daria Kasatkina, with whom she ended the Santina Streak. Kasatkina started the year with a win over the elder of the Williams sisters at the ASB Classic, and could be seen supporting her partner from the stands.

“She told me a couple of things before the match, but she said, ‘That’s Venus; you have to expect everything,'” Vesnina said when asked whether her countrywoman had given her any advice. “It was great to have her in my player box alongside my husband and my dad.

“The center court atmosphere was really amazing. Even though I felt like Venus was the favorite and everyone really wanted her to win, there will still some people cheering for me, so that was really nice. It’s great when you can have a big team behind you, supporting you and believing in you.”
