Paire has won both their previous meeting. Their last match was in November last year on an indoor hard court and he won in 3 sets.
Mathieu usually makes it past the first round at this tournament but he has never won 2 matches there.
Paire reached the final in 2013 but lost at this stage last season. In his 3 previous visits to this event he has never lost as favourite. He seemed a little more focused last season once he recovered from his injury.
I will be waiting for 1.75 on Paire but I think he takes a tight match.
