And though she offered up a fairly simple fix to that problem - "win matches" - that's been easier said than done for Canada's top women's singles player lately. Eugenie Bouchard of Westmount, Que., plays Croatian qualifier Donna Vekic in the afternoon.
"It was definitely a humbling experience and a bit of an eye-opening experience as well to see, obviously, the difference in the level of the tournament", Bouchard said.
In other first-round action, Daria Gavrilova beat Lara Arruabarrena 6-3, 6-3, Daria Kasatkina got past Roberta Vinci 7-6 (3), 7-6 (1), and Naomi Osaka advanced after Heather Watson retired in the second set, taking the match 6-1, 4-1. "I watched her match at Wimbledon against (Johanna) Konta". "From the first round, you really have to play your best game to win". She also had 19 unforced errors to Vekic's 10. She would save the first, but netted her backhand on the second to gift Wozniacki the break back and a 5-3 lead. "I kind of got to find my rhythm in the beginning but thought I served and returned very well", Wozniacki said.
In the final match of the evening, Montreal's Francoise Abanda was dropped in straight sets by Lucie Safarova of the Czech Republic.
"She's a good player", Bouchard said.
"But, you know, I relax".
The 23-year-old Bouchard, who made a name for herself when she reached the Wimbledon final in 2014 after two straight Grand Slam semifinal appearances, has failed to make it past the second round in six straight tournaments.
Asked if she'd prefer that fans and media ease up on her, noting she's still young enough to turn her career around, Bouchard replied "yes and no". Yes and no. I mean, I guess I'm relatively young, but I feel old in a way. You know, people just walked up and there were just so many huge differences. That would be the worst thing I could do.
"Two from three (Grand Slam finals) is awesome so I still think she has a chance to win a Grand Slam and she still has the power to win any of the tournaments", World No. 1 Karolina Pliskova said of Williams during a media session earlier Monday. Her best showing at a Rogers Cup came a year ago in Montreal, when she lost to Slovakia's Kristina Kucova in the third round.
Wozniacki pummeled her opponent's serve in this match, limiting Alexandrova to 56 percent of her first serve points won. "I was like, "Please, let me get this one" and I managed to".
In reality, Bouchard has turned to playing doubles to keep up her match fitness, and found success later in the day after her singles loss, as her and her partner Karolína Plíšková defeated Dominika Cibulkova and Kirsten Flipkens 6-4, 6-2.
Ekaterina Makarova, Catherine Bellis, Magdalena Rybarikova and Barbora Strycova are also through to the second round.
