Deuce – DOUBLE FAULT!

Another long rally sees Zverev dictate from the back of the court but Fritz stays with him and then forces the error through sheer force of will.

Shot! The rallies are lengthening as both players dig deep, the ball pinging back and forth an inch over the net, Zverev then opens his body and whistles a backhand winner as pure as an alpine snow drift. Clean and crisp.

This game is a battle. “It’s a backhand clinic” says Laura Robson on the commentary. Both players are slugging it out as the game ticks up past eight minutes in length. Fritz chastises himself as a ragged forehand goes long and returns him to deuce. Whoever wins this game mught well win the match. Zverev’s turn to admonish himself as he wastes an opportunity on the backhand side with plenty of court to aim at.

And Fritz HOLDS! That is huge for the American. He was 0-40 down and went back and forth on deuce. Could have been curtains if that one had got away, but it didn’t.

Third set: Fritz 6-3, 3-6, 2-2 Zverev*

Speaking of epic! A 32 shot rally has the crowd on tenterhooks, neither player flinching until Fritz misses the baseline by a smidge. Easily the best exchange of the match. Zverev then bangs down a speedy ace to take the game. Phew.

Second set: *Fritz 6-3, 3-5 Zverev

Fritz makes Zverev come out to serve for it, he’s still having success in the longer rallies and can pick up cheap points on serve. If we do go to a decider, and it looks like we will, the the American still has a good chance of creating an upset. Zverev has not looked as comfortable on court today after a serene week.

Second set: Fritz 6-3, 1-2 Zverev*

The lights in the stadium flicker as Zverev goes through his service motion. Need a new bulb back there, lads. The umpire halts play and calls for them to replay the point.

Second set: *Fritz 6-3, 1-1 Zverev

A long delay accompanied by plenty of whoops and jeers as the umpire calls ‘not up’ on a Zverev backhand. It takes an age to get the side angle but the call is eventually overturned!

Remonstrating with his box with shoulders slumped. Fritz will be loving this. The German hasn’t gone full Harry Enfield’s Kevin the Teenager but he’s not far off with the first set slipping away quickly.

First set: Fritz 4-2 Zverev*

Here we go, 15-30 and some heat on the Zverev serve as he misses a couple of first serves and Fritz steps up to the seconds. Zverev misses another first serve but the second is well placed and has him able to come to the net and finish the job. 30-30. What a rally! Fritz drop shots and then follows up with a lob, Zverev juuuust reaches it with a backhand overhead but Fritz blasts the passing shot to bring up the first BREAK POINT of the match at 30-40!

Zverev makes it to deuce with a fine pass of his own. The standard of tennis is extremely high. FRITZ BREAKS! For the first time in the tournament Zverev loses his serve and he looks incredibly shocked! Well played Fritz who stepped up, went for the line and grabbed the game.

Big serve down the T and smash to follow up from Zverev. Well placed serve out wide next up and Fritz’s return finds the top of the net. A rally! Both players covering plenty of ground, Zverev tries a drop volley but Fritz gets there and makes the pass, even Zverev and his albatross wingspan can’t reach it. Both players hitting plenty of first serves, not much time to draw breath, or type for that matter.

First set: *Fritz 2-1 Zverev

Another rapid hold on serve by Fritz as I frantically google synonyms for ‘booming’.

First set: Fritz 1-1 Zverev* (*denotes server)

You know the drill. Zverev has served and volleyed like a dream all week and he shows off brute power and Andrex soft hands. A comfortable hold for the German. Both men rattling through their games.

First set: *Fritz 1-0 Zverev (*denotes server)

Fritz sends down two booming aces and takes the first game. Zverev tried a dinky drop shot that didn’t come off but did get a point with a rasping cross court backhand.

Righto, first set incoming. Fritz to serve!

Be still my beating heart:

Both men are sporting a Roger Federer style bandana, neither has opted for Rog’s cable knit cardigan though. Remember that? Peak Fed.

Zverev looks steely and focused, he’s in some of the best form of his career so far. Taylor Fritz wins the toss and elects to serve. Both players have absolute gun serves, we might be in for some tie breaks, I can’t see too many breaks of serve in this match.

Tim Henman thinks Zverev will take this one, he’s almost drowned out by the stadium DJ and accompanying strobe show. Which can only mean one thing, here come the players.

Home favourite and top seed Jannik Sinner will face off against Norway’s Casper Ruud in the second semi final this evening and we’ll be bringing you that game live too. Ambassador, liveblogger, you are spoiling us.

Sinner hasn’t dropped a set so far in the tournament but Zverev can best that, having not even been broken in his three matches so far.
