As the WTA event in Rouen, known officially as the Open de Rouen, continues on Friday, there is a rather intriguing clash between Marta Kostyuk and Ann Li. This is clearly a match between two players who are quite similar in terms of all-round quality. In other words, it's quite difficult to see either player as a sizable favorite, let's be honest. 

Both players arrive off the back of confidence-boosting wins during the previous round, but neither Kostyuk, no Li could get the job done in straight sets, nor has either made a habit of losing in straight sets over the last few months. Given what we've seen from each player in recent times, a bet on this match to go the distance in terms of sets is a wise move at odds of +175.

Our Marta Kostyuk vs Ann Li Prediction

At the end of the day, there really isn't much between these two, as the rankings would suggest. Moreover, they have a clear pattern of playing out tight matches, matches that go the distance. With this in mind, 'Over 2.5 Sets' looks to be a little bigger than it should be. To be honest, if such a bet was priced at +133, would anybody blink? Almost certainly not. Odds of +175 are definitely worth taking. 

Our Marta Kostyuk vs Ann Li Pick: Over 2.5 Sets.
