Eugenie Bouchard claimed she had the support of the tennis world after matching her fighting talk with some thrilling tennis to shock Maria Sharapova 7-5, 2-6, 6-4 in the second round of the Madrid Open on Monday.

Bouchard called Sharapova “a cheater” last week and was also critical of the Russian’s welcome back to the sport after a 15-month doping ban with a series of wildcards for big events.

The world No 60 admitted she was extra motivated to face her former idol and it showed with signs of the form she has lost over the past few years since reaching the Wimbledon final in 2014 in a bruising near three-hour contest.

“I was actually quite inspired before the match because I had a lot of players coming up to me privately wishing me good luck,” said Bouchard. “Players I don’t normally speak to, getting a lot of texts from people in the tennis world that were just rooting for me. I wanted to do it for myself, but also all these people. I really felt support. It showed me that most people have my opinion, and they were just maybe scared to speak out.”

Sharapova claimed to have not been distracted by media circus surrounding the match and that her disappointment comes from losing, not who she lost to. “I think I would be worried about myself if I sat here and said I’m pretty happy with losing a tennis match, no matter who I face, no matter what round it is, whether it’s the first round or final of a Grand Slam,” she said.

“I’m a big competitor. What you work for so many hours every single day is to be on the winning end of matches. Today was just not that day. Of course, I’m disappointed. That’s what’s going to make me a better player. That’s what’s going to win me more tournaments and more Grand Slams.”

Topsy-turvy

Bouchard battled back from 4-2 down to claim a topsy-turvy first set and she edged a marathon 11th game before serving it out for just her second set in five meetings with Sharapova. However, adversity brought out the best in the five-time Grand Slam champion as Sharapova found the precision to match her power in the second set, reeling off four straight game from 2-2 to level at one set all.

Both players struggled to hold serve in the deciding set as a total of 14 break points were squandered. However, Bouchard held her nerve when serving for the match at 5-4 as she saw off two break points and an unfortunate let cord on her first match point. The Canadian jumped for joy after delivering the final blow before the two exchanged a very frosty handshake at the net.

Bouchard will face top seed Angelique Kerber, who fought back from 5-3 down in the deciding set to overcome Katerina Siniakova 6-2, 1-6, 7-5 earlier on Monday, in the third round. Kerber has had an inconsistent season and her fragile form was on show in the course of the first two sets. The German romped through the opening set in 27 minutes but then had to save six break points for her only game in the second. Siniakova served for the match at 5-4 in the deciding set, but Kerber should impressive fight to win the last four games.

World No 3 Karolina Pliskova was dumped out 6-3, 6-3 by Latvia’s Anastasija Sevastova. In the men’s Madrid Masters there were comfortable wins for Thomas Berdych, Grigor Dimitrov and Nick Kyrgios. However, 15th seed Gael Monfils bowed out in a wild match against French compatriot Gilles Simon 0-6, 6-0, 7-6 (7/0). Andy Murray begins his quest for a third title in Madrid on Wednesday when he faces Romanian Marius Copil.
