US Open tennis day five acca: free accumulator for Flushing Meadows

The Racing Post's tennis experts will select their best multiple bet for the US Open every day. Here is the day five acca bet.

Stan Wawrinka to beat Paolo Lorenzi

There has been good support for Paolo Lorenzi, who has made the most of his lucky-loser status in New York, to continue in winning vein over Stan Wawrinka. But if anything the Swiss ace is getting better as the season goes on and he's still likely to take plenty of stopping.

Ashleigh Barty to beat Maria Sakkari

Ashleigh Barty is having to knuckle down to things more in the second half of the season than the first, but the Australian should still find a way to progress with a victory over Greek number one Maria Sakkari.

Serena Williams to beat Karolina Muchova

Serena Williams fought back from the loss of the opening set to defeat Caty McNally but the running could be smoother for the American legend against Karolina Muchova. The Czech is making serious strides but Williams should prove different class.

Karolina Pliskova to beat Ons Jabeur

Ons Jabeur continues to work wonders and did supremely well to outplay Aliaksandra Sasnovich in round two but Karolina Pliskova, one of the most consistent performers in women's tennis, could be a bridge too far for the gallant Tunisian.
