Pick 8: Over 3.5 sets (1.5 Pinnacle)

Former champion Stan Wawrinka had a real struggle on his hands in the first round. After winning the first two sets against Albert Ramos Vinolas, he need to win the fifth set to progress. That took him over four hours while his opponent had a much shorter match. Kokkinakis beat the 20th seeded Daniel Evans in straight sets. I believe that match will go to distance and my Stan Wawrinka v Thanasi Kokkinakis prediction is for over 3.5 sets at the odd of 1.50.
