Laura Siegemund and Naomi Osaka meet in the first round at French Open on Tuesday. Naomi Osaka brings a 3-match winning streak into this one, 7-3 across the last ten. Laura Siegemund comes in at 5 wins from the last ten.

Naomi Osaka has had the better of this rivalry, winning 3 of 4 against Laura Siegemund. On clay specifically it reads 2-1 Osaka — worth more than the overall number this week.

The serve is where this match separates: Osaka has been winning 70.9% of first-serve points to Siegemund's 59.3%, and on clay that gap compounds fast. Anything other than a Osaka win would rank among the bigger surprises of the week.
