It was really solid play from Fearnley in the beginning of the fourth set and in the late part of the third set. Unfortunately, just when he was trying to put the pedal down, a few unforced errors came and gave Etcheverry a chance to get back into the match.
But a pretty solid tournament for Fearnley.

Then, a double fault. Two break points!

Yet another double fault from Jacob Fearnley for 30-all - his 11th of the match.

Huge service game coming up for the Brit.

A messy, messy service game from Jacob Fearnley.
