Norfolk's Alfie Hewett through to Wimbledon wheelchair singles final
The duo had faced off at Roland Garros last month with Fernandez successful in the last four, but Hewett claimed revenge with a 4-6 6-4 7-5 semi-final win against the third seed.
Alfie Hewett is one victory away from a maiden Wimbledon wheelchair singles title after he downed Gustavo Fernandez in a thriller on Court Three.
The duo had faced off at Roland Garros last month with Fernandez successful in the last four, but Hewett claimed revenge with a 4-6 6-4 7-5 semi-final win against the third seed.
Victory after two hours and 41 minutes kept Hewett on track to claim a first singles triumph at the All England Club after runner-up finishes in each of the last two years.
Hewett had battled with a shoulder problem during his quarter-final win over Stephane Houdet and struggled early on against Fernandez, being broke twice to trail 4-1.
The second seed rallied in trademark fashion, but the Argentinian still had enough to seal a 46-minute first set.
When Fernandez claimed a break at the start of the second and subsequently raced into a 3-1 lead, Hewett appeared in trouble.
However, the eight-time grand slam singles champion dug deep to win four games in a row before a sumptuous backhand levelled up the match.
Breaks were exchanged at the start of a dramatic decider, but Hewett secured a pivotal break in the 11th game before he closed out victory on his sixth match point.
