Our Elise Mertens vs Naomi Osaka Prediction
The Difference Maker: Osaka arrived in Toronto already in tip-top form after reaching the semifinals at Washington. She proved just that with a relatively easy win over Panna Udvardy.
Meanwhile, Mertens shook off a rusty start to beat Anna Bondar.
What to Expect: Osaka gets off to a hot start, wrapping up the first set in under an hour before putting the finishing touches to defeat Mertens in straight sets.
Mertens is a dangerous player at any stage of a tournament, but Osaka’s hard-court game is peaking up quite nicely.
Fearless Forecast: Naomi Osaka wins 6-3, 6-3
Our betting prediction for Naomi Osaka vs. Elise Mertens: Naomi Osaka -5.5 games
