US Open tennis day four 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-four fourfold:

Andrey Rublev to beat Gilles Simon

Andrey Rublev appears to be over his injury problems and was in fine form in beating Stefanos Tsitsipas on Tuesday. The Russian should have no problem dealing with Gilles Simon, who lost three consecutive matches in the build-up to the US Open.

Nick Kyrgios to beat Antoine Hoang 3-0

Antoine Hoang made the most of a wildcard from the French Tennis Federation to beat Leonardo Mayer in the opening round but Nick Kyrgios represents a far tougher test. The Aussie won the ATP Citi Open earlier this month and can brush aside the Frenchman.

Simona Halep to beat Taylor Townsend 2-0

Wimbledon champion Simona Halep needed three sets to beat Nicole Gibbs but should have no problem dismissing Townsend. The Romanian star has beaten the American 2-0 in all three of their meetings, never dropping more than four games in a set.

Jelena Ostapenko to win at least a set against Alison Riske

Jelena Ostapenko won the 2017 French Open and, while it has been hard going for the Latvian since, she should make a game of it against Alison Riske. Wimbledon quarter-finalist Riske struggles in New York – a first-round victory was only the fourth Flushing Meadows win of her career.
