If they get through, Neal and Christian would play Martinez and Munar in round 2, which I think could be quite tricky.
Nys and Roger-Vasellin have lost in round one, the 8th seeds. They lost to Argentinians and two Argentine pairs play each other in round 2. Looking at the early results, I wonder how generally the courts are playing in terms of speed - is it possible they are a bit slower this year?
