The ferocity of Fearnley's forehand increased, finding more speed and depth to trouble Fonseca, while also stepping further into the court to attack the Brazilian's second serve.

The adjustments were illustrated by three whopping forehand winners - including one at 89mph - which secured a double break on his way to levelling the match.

Fearnley's momentum enabled him to move an early break up in the decider but Fonseca showed he possesses the mental strength, as well as the technical talent, needed to climb even higher in the rankings.

Fonseca reasserted his authority in the baseline exchanges, applying enough pressure on Fearnley's serve to draw out two double faults and break back for 3-3.

With plenty of vocal Brazilian fans behind him, Fonseca maintained the momentum as he underlined why he is being predicted to reach the very top.
