A Search for Surprisingly Sparse Head-to-Heads
Small sample size is typical of head-to-heads in pro tennis. Both seeding and knockout tournament designs mean that many pro players have played each other no more than a handful of times or sometimes never at all. Still, I find myself frequently surprised when I come across sparse head-to-heads between some seasoned players. It got me thinking if that reaction is even reasonable and how you might quantify how much some matchups are overdue?
