OK. if we consider them by today ranking (I think David's today's condition is really at the correct place 85):
David's 85 vs Pico's 20,
then Pico will win like 6-3, 6-1...
we can only hope (because of David's Nr3 in the past,
yeh, Pico had not never such position,... because Dave's talent, and finally because we are his fans
and wish - David will win 6-3, 7-5
yes, i remember how nicely David could beat such clay specialist like Guga
