*Shapovalov 3-4 Edmund
Kyle Edmund is backed into a corner at 30-30, there's only one way out of this tight spot. An ace. Another big serve leaves Denis Shapovalov scrambling, Edmund wrapping up the hold.
Still on serve, still no sign of a break.
Shapovalov 3-3 Edmund*
Denis Shapavalov hasn't dropped a point on his serve yet. A shank from Kyle Edmund sees that continue for 15-0.
Then Edmund is level without moving off the baseline. A double fault reveals the first sign of nerves from the Canadian teenager, before a long forehand and another miscue from Edmund puts Shapovalov 40-15 ahead.
The Brit claws back another point, only for Shapovalov to seal the hold by galloping forward and patting down a high volley.
*Shapovalov 2-3 Edmund
Kyle Edmund has got weapons - but not always in his mind. Denis Shapovalov has a sniff at 30-15, only for Edmund to bang down a meaty serve down the middle.
Five holds, 12 minutes. Any of you lot needing an early Sunday night ahead of a busy Monday morning? You could be in luck.
Shapovalov 2-2 Edmund*
Wow. Denis Shapovalov, who took the Wimbledon junior title last year, blitzes Kyle Edmund with another hold to love.
Our man John Lloyd has just made that comparison between tennis' great teenage male - Boris Becker. Big.
*Shapovalov 1-2 Edmund
Nothing being offered up at either serve in these early stages. Kyle Edmund also notches up a hold to love.
Edmund was pushed around the court by Vasek Pospisil in Friday's singles match. That shouldn't happen tonight.
Shapovalov 1-1 Edmund*
Denis Shapovalov shows Kyle Edmund he can play. The fresh-faced Canadian, grungy blond hair poking out of his white snap-back cap, holds to love.
*Shapovalov 0-1 Edmund
When I was 17 I was trying to skulk past bouncers and get into Yorkshire nightclubs. Denis Shapovalov is playing in a Davis Cup world stage deciding rubber. What a talent.
Kyle Edmund takes on the role of a beefy, suited 'door security' in the first game, keeping Shapovalov from sticking his nose into the fun. Two big opening points set the Brit on the way to a comfortable hold.

It’s tough to call how this will play out. Obviously Kyle Edmund is the heavy favourite with his experience, but he had such a disappointing first rubber against Pospisil when he was extremely nervous. Shapolavov hit some great shots against Dan Evans but had no game plan really. I think Kyle will come through but it could be a bit of a nervous match.
Shapovalov 0-0 Edmund*
Kyle Edmund to kick off this deciding rubber. Hold on tight folks...
Canada 2-2 Great Britain
The DJ presses play on some dramatic 'mood music' as Kyle Edmund wanders out into the TD Place Arena, followed shortly after by Canadian teenager Denis Shapovalov.
Edmund is ranked 47th in the world, almost 200 places above his talented - but inexperienced - opponent.
Both men (well, boy in Shapovalov's case) lost their singles matches on Friday in straight sets.
Canada 2-2 Great Britain
Great Britain and Canada already know the prize at stake - a trip to France in the Davis Cup quarter-finals.
The French won their tie against Japan, who were without Kei Nishikori, with a day to spare after Nicolas Mahut and Pierre-Hugues Herbert won the doubles to give them an unassailable 3-0 lead.
A win for Kyle Edmund gives the French chance of revenge for that memorable beating at Queens in 2015.
So, it's a decider then. All down to Kyle Edmund and Denis Shapovalov. Will it be the Brit or the teenage Canadian who sends their team through to the quarters?
Shapovalov, chunky headphones wrapped tightly around his neck, shuffles his way out of the Canadian courtside box back into the locker room. He needs a racket or two.
Back soon...

Huge credit to Pospisil. He played a tough doubles yesterday, had a great win on Friday. From Dan Evans point of view, he’ll be disappointed. I don’t think he played a bad match but you look at the first set and the fourth set, it’s not a match where he didn’t have his chances. But Pospisil played the big points better and stuck to his game plan.
Pospisil 7-6 (7-3) 6-3 3-6 7-6 (7-5) Evans
But Dan Evans can't save the second match point. Vasek Pospisil clinches the fourth rubber when Evans can only pat his serve into the tramlines.
The TD Place Arena erupts, Pospisil laps up the plaudits.
Pospisil 7-6 (7-3) 6-3 3-6 6-6 (6-5) Evans*
Evans serves...ACE! One match point saved by the Brit...
Pospisil 7-6 (7-3) 6-3 3-6 6-6 (6-4) Evans*
Pospisil batters a forehand cross-court. Does it dust the line? Yes. Evans goes to the technology. It doesn't save him.
Two match points...
Pospisil 7-6 (7-3) 6-3 3-6 6-6 (5-4) Evans*
Second serve Pospisil...Evans clubs a return long. Pospisil screeches. He's two points away from the match.
