I think the manner of how Arthur Fery lost the first-set tie-break, plus the level at which both players have started the second set, has knocked the stuffing out of the Centre Court a bit.

Alexander Zverev gets to a drop shot and bunts it down the line for a winner - two more break points for the French Open champion.

You get the feeling that Alexander Zverev is starting to bully Arthur Fery from the back of the court.

Alexander Zverev has hit 24 winners and 23 unforced errors in this match.

For Arthur Fery, it's five winners and 14 unforced errors.

Fery is again over to the chair umpire claiming that one of Zverev's serves clipped the top of the net and was not called a let.

Zverev holds serve easily and this match might get away from Fery quite quickly if he's not careful.

The forehand winner by Zverev to clinch the game was 103mph, according to commentator Andrew Cotter. Good luck getting that back.

That was the fifth time Alexander Zverev has won a tie-break to love at a Grand Slam - it is also Zverev’s second tie-break victory to love at Wimbledon this year, after winning one 7-0 in the opening round against Alexander Blockx.

We spoke before the semi-final how important Alexander Zverev's serve might prove to be.

He got 76% of his first serves in - up on his tournament average - during the first set but Arthur Fery did break him once.

It's just gone a little bit flat on Centre Court so it's important that Arthur Fery holds on to his serve and gets the crowd engaged again.

Arthur Fery needs to do what he's done three times already this fortnight... fight back from losing the first set.

And, don't forget, he was also two sets to one down against Grigor Dimitrov in the fourth round.

Only a fool would rule Fery out at this stage, but we know Zverev is a completely different proposition to his previous opponents.

If Alexander Zverev times the ball like he did on that serve, he is going to be in the final.

That tie-break will hurt Arthur Fery, who had matched Alexander Zverev throughout the first set and then his chances of winning it disappeared in an instant.

But history would tell us this semi-final is far from over.

Fery lost the first set in each of his first three matches at this year's Wimbledon, while in the fourth round he trailed Grigor Dimitrov by two sets to one, and the Briton came back to win all of those matches.

Zverev looks a different proposition for Fery today, though.
