Serena Williams comes from behind to reach the US Open semi-finals, while the men’s singles finally enters the 90s – but how much could tennis spread betting fans have won?

Who will Serena Williams face in the US Open semi-finals?
For a moment there Williams had a wobble. The living legend lost her first set against Tsvetana Pironkova 6-4, before comfortably bouncing back to win the 2nd and 3rd sets 6-3 6-2.

That did mean, if you sold a Set 1 Williams/Pironkova 10-3 Supremacy spread of 11-14 – that’s were its 10 points to the winner of the set, plus a further 3 points for every game won by – a makeup of -16 left you with 27 times your initial stake.

The Bulgarian’s surprisingly strong open also meant Total Games came in at 27. Buy at a starting price of 20.5-21.5 and that’s 5.5 times your opening bet.

Similarly, Total Points overshot expectations, coming in at 185 against an initial spread of 131-136. That’s 49 times your original wager.

When was the last time Serena Williams won a Grand Slam? That’d be 2017’s Australian Open. Her last US Open championship, meanwhile, was 2014. Victory in 2020 would also see her finally draw level with Margaret Court, at 24 Grand Slams apiece.

Williams is now set to face the unseeded Victoria Azarenka in the semi-finals. It’s a tough one to call, with Spreadex offering a choice Williams/Azarenka Match Supremacy spread of -1.5-1.5.

Victory would likely set up a final against Naomi Osaka, a re-match of 2018’s controversial US Open climax.

Who are the men’s US Open semi-finalists?
Thanks to Djokovic’s messy exit, for the first time ever the tennis world is going to see a male Grand Slam winner born in the 1990s.

2019 US Open runner-up Daniil Medvedev secured a consecutive spot in the semis with a straight sets win over fellow Russian Andrey Rublev. Buy at a starting Medvedev/Rublev Match Supremacy spread of 11-14 – where its 10 points for the winner and a further 5 points for every set won by – and makeup of 25 left you with 11 times your opening stake.

He will face no. 2 seed Dominic Thiem, who saw off Alex du Minaur with minimal fuss, winning 6-1 6-2 6-4. Buy a Thiem/de Minaur Game Supremacy spread of 3.5-5, and you also came away with 11 times your original bet.

As for their semi-final, the Russian is narrowly the favourite, at a Medvedev/Thiem Match Supremacy spread of 0.5-3.5.

In the other side of the draw, no. 5 seed Alexander Zverev will take on Pablo Carreno Busta – the man who inadvertently knocked out Djokovic. Both are looking for a Grand Slam final debut, with the German heavily favoured at a Zverev/Carreno Busta Match Supremacy price of 8.5-11.5.
