Hopefully in the back of Jacob Fearnley's mind is an awareness of his opponent and what he can do and is comfortable with but also maybe not so comfortably doing - which is when Etcheverry is attacked, he drifts way deeper behind the baseline just to give himself more time to see the ball and to try and load up.

I expect if Fearnley does get to net, that we're going to see a few drop volleys put in play.
