Pick 5: Jan-Lennard Struff to win 2-0 (1.70 Unibet)

Jan-Lennard Struff, last year a Stuttgart finalist, knows how to play at home in Germany. He should have lots of momentum after shaking off rust in his opening match, where he beat Flavio Cobolli 7-6 (7) 6-3. The smooth Arthur Rinderknech will pose a different challenge for the German, as the Frenchman has a big serve and can attack the net well  making him more of a threat on the grass than the Italian. Struff will have to return well and take advantage of break points, but ultimately he can serve that much bigger than the Frenchman and he is no slouch at the net either.
