As the post-Andy Murray era begins, the British squad for the men’s team event has a fresh look and new impetus.

Former world top-10 player Cameron Norrie is also missing through injury and that has resulted in Harris – joined as a rookie in Smith’s squad by Wimbledon doubles champion Henry Patten – being rewarded for his stunning rise over the past 18 months.

Harris’ journey to the cusp of the world’s top 100 has been long and arduous.

Driving around Europe to play in lower-tier events, and sleeping in his van while parked in McDonald’s car parks, stood as testament to his dedication.

The perseverance has paid off.

Harris was a hitting partner for the British squad when they played in the Davis Cup Finals knockout stage in November – now he is playing a pivotal role in their quest.

The bedrock of Harris’ game is his first serve, which he demonstrated in an impressive opening set where he won 95% of those which he landed.

Virtanen, ranked just below the Briton at 110th in the world, struggled with his returning game as a result, and it was a similar story as Harris moved a break up in the second set.

A change of flux saw Harris let the lead slip but, by maintaining his composure, he recovered to take control of the tie-break and earn an impressive victory.

Asked where this ranks among his finest career moments, Harris said: “I think making my debut for Great Britain and winning on my first cap probably tops it all so far.

“Three years ago I was probably ranked about 600 so I had no chance of getting near the team.

“But I’ve been improving each year since then and feel like I was ready to step into the team once I got called up.

“It’s a very proud moment to represent my country and happy I put in a good performance.”
