There's an all-top-25 clash due to take place in Toronto on Thursday, when world number 11 Marta Kostyuk takes on world number 23 Madison Keys. The pair will face off for the third time as pros. Keys has won each of the previous two renewals of this match, and after she defeated Antonia Ruzic in straight sets during the first round, she'll fancy herself to get the job done. 

The early betting market favors the Ukrainian, who made a pleasing return to hard-court action with that win over Katherine Sebov last time out, but let's not pretend that this isn't a much tougher assignment. Madison Keys defeated much better opponent in straight sets during the first round, while the American has a pleasing record against Kostyuk, so much so that we can conclude that she's a little generously priced here. After all, she has previously reached the final of this event.

Our Marta Kostyuk vs Madison Keys Prediction

Plainly, Madison Keys is worthy of stronger support than the time-of-writing odds would suggest. Sure, Marta Kostyuk is narrowly ranked above Keys, but don't focus too much on that. As touched on above, Keys achieved more than her opponent during the first round, while the Ukrainian does not have a positive record against the American, who has not only won each of the previous two renewals of this fixture but has done so without dropping a set. On that basis, she should be priced a little shorter than +110.
