They don't reward "good" losses in pro tennis, but ...
... I feel compelled to remind you that the man whom John Isner lost to in a fourth-set tiebreaker in the first round of Wimbledon, Ernests Gulbis, is no slouch.
As I type this, he is on serve in the fourth set against world No. 2 Rafael Nadal. Gulbis won the first set, lost the second and then fell in a third set tiebreaker.
I don't think he'll pull the massive upset, but he's really making Nadal work.
So again, no shame in Isner's loss. But, unfortunately, not ranking points either.
