Belinda Bencic of Switzerland have cracked the code, leading to a 6-4, 6-0 win over Alex Eala in the Round of 16 of the Canadian Open last Monday at the Sobeys Stadium in Toronto.

Bencic said facing another left-hander, world No. 110 Taylor Townsend of the United States, in the previous round helped her prepare for the 21-year-old Filipino sensation — the hottest player on the tour with seven consecutive victories.

Bencic, who now has won 10 consecutive matches against left-handed players, needed just 73 minutes to dispatch Eala and book a quarterfinal berth in the prestigious Women’s Tennis Association (WTA) 1000 tournament.

“Yeah, I mean, I think with every lefty it’s a little bit trickier to return. I’m really happy with the way I returned. I think it’s maybe one of my biggest strengths, so I think that helps,” Bencic said.

“I’m also glad that I played a lefty at the round before. I felt like I had a little bit more problems against Taylor with the serve. But, yeah, we had a really good performance today.”

The former world No. 4 and Tokyo Olympics gold medalist said she was well prepared for Eala’s left-handed game, which she described as a mirror image of her own.

“I think obviously it’s always tricky to play a lefty, so I was really prepared for that. I was prepared basically for the opposite. It’s like a mirror, you know, everything is opposite, the spins and everything. But I feel like I solved that pretty well and I felt good in my rhythm,” Bencic said.

“But, of course, she plays really good. I feel like she takes the ball early as well like me so I think that’s a little bit similar in our games.”

Videos of Bencic fuming at a cheering crowd in a previous tournament had circulated online before the match, raising questions about how she would react to a sold-out venue that is packed with mostly Filipino fans rallying behind Eala.

But instead of having a meltdown, Bencic remained composed and embraced the pressure-packed atmosphere.

“Obviously I know they were cheering for her, which was super nice, and the atmosphere was great. So I kind of just tried to focus on myself, and also embrace it like for myself,” Bencic said.

“I was mentally prepared, but it’s not something that bothers me so much.”
