The semi-final picture here at the Rogers Cup in Toronto is looking a little more clearer as China’s Li Na defeated Dominika Cibulkova of Slovakia in straight sets (7-6 (1), 6-2) this afternoon.

Winner of the 2011 French Open and finalist at the 2011 and 2013 versions of the Australian Open, Li Na had a promising showing this afternoon despite a slow start.

Li Na will now await the winner of the Petra Kvitova/Sorana Cirstea matchup in the Rogers Cup semi-final on Saturday.

One of Na’s potential opponents on Saturday is Petra Kvitova. Na knows Kvitova fairly well as she defeated the Czech in last summer’s final at the Cincinnati Open. Na was asked of her memories on her potential adversary.

“I mean, every time I was play (sic) Kvitova, always tough match,” Na said. “Because I think we play pretty similar.”

Of course, as of now, Kvitova is battling with Romania’s Sorana Cirstea in her quarter-final matchup. So, if the Romanian has any of say, the Czech veteran may not even get to play on Saturday.

In terms of how she’s spending her time away from the court, Na mentioned that she’s only been to Chinatown twice while she’s been in Toronto.

“Yeah, because I have three days I didn’t eat the rice, so yesterday I was, like, No, I have to go. Otherwise, I was feeling I lose energy, you know.”

So, there you have it. The secret to Li Na’s success is her consumption of rice. Perhaps many restaurant establishments both in Toronto and other cities which host tennis tournaments will take note and help determine whether Na wins or loses.

Relax. It’s just a theory.
