Arthur Fery beat Giles Hussey 6-3 6-2 in the final of the M25 Sheffield to secure the championship after a week of tennis in the city.
The 20-year-old, who sat in 656th in the ATP rankings before the start of the week, was able to win six consecutive games after the match was tied at 3-3 in the first set to assert his dominance on the encounter.
The former world number 12 at junior level showed his class in a superb performance, eventually cruising to victory in straight sets in the ITF event.
Story of the match

The 25-year-old managed to continue his good start serving from the right-hand side to win advantage three times, but failed to close out each one having had momentum in each of the points.
On the fourth advantage, Hussey was able to hold his serve on the volley to win the first game of the tie.
Two unforced errors in Fery's first game on serve left the score at 30-30, but he was able to see out the game confidently in the end, winning the next two points.
The man who beat Sean Hodkin in the semi final of the M25 Sheffield event held his serve to make it 2-1 to Hussey soon after.

A great forehand from Hussey down the line brought up deuce on Fery's serve.
A wonderful passing shot from the receiver gave Hussey break point, but Fery roared back, winning three consecutive points to win the game and make it 2-2.
The 20-year-old, who won his first ITF event in August, had three break points but squandered his chance to take control of the opening set initially.

A break up, the man who had not dropped a set all week found himself 0-30 down on serve and failed to consolidate his lead, as Hussey made it 3-3.
The theme of both players failing to hold serve continued though, as Fery went ahead again.
Fery takes control

The game that followed was tense, as Hussey looked to grow into the game.
