Talking of the man - he was again court-side, and was right in the thick of the celebrations - surely the future of British tennis once Murray is done winning Slams and the BBC Sports Personality of the Year award is in good hands?
Andy Murray admits that he has been surprised by the rapid progress of Kyle Edmund, who guided Great Britain to the Davis Cup semi-finals over the weekend.
Edmund, aged 21 and playing in only his third Davis Cup rubber, carried the nerves of the nation and after just a few understandably anxious moments, won in straight sets to seal a 3-1 victory for the holders.
Edmund proved he was a big-occasion player, but more importantly the team proved they could go on and win without talisman Murray on the court.
World number 10 Tsonga beat 50th-ranked Vesely 4-6, 7-6 (7/3), 6-4, 7-5 in three hours and 28 minutes as France won on Czech soil for the first time in 90 years.
Delbonis, the world number 40, had also pocketed the first point on Friday by beating Andreas Seppi, the world 52, before Fognini saw off Juan Monaco in straight sets to level the quarter-final.
Next up is a home tie against Argentina in September where, with Murray having already said he is planning to take part, Britain would be favourites to advance to the final for the second year in a row.
A game later Edmund broke through again to lead 4-3 and then converted his first set point at 5-4 when he fired down another giant serve. He and Guido Pella looked ready for a straight-sets win over Fognini and Paolo Lorenzi, but the Italians battled back to level the match before del Potro and Pella edged the deciding set after nearly four hours. The only hiccup came when Edmund was serving for the match in the third set.
Jo-Wilfried Tsonga overcame an early scare to win the opening reverse singles to give France a 3-1 victory over host Czech Republic at Werk Arena in Trinec.
The Serbian then had two chances to take it to a fourth set but Edmund saved them both and recovered from 4-2 down in the tie-break with some big forehands.
Amid increased security following the deadly attack in the French city of Nice, Tsonga rallied to beat Jiri Vesely 4-6, 7-6 (3), 6-4, 7-5 and earn a spot in the Davis Cup semifinals for France for the second time in three years.
I am sure he will take a lot from going out and winning matches of this intensity, under such pressure.
In their quest for a first Davis Cup title since 2001, France will now face either the United States or Croatia in the semifinals.
Borna Coric defeated Jack Sock 6-4, 3-6, 6-3, 6-4 Sunday in the fifth and final rubber to book the semi-final berth for Croatia in Portland, Oregon.
The U.S. -Croatia victor will host the semifinal against France.
