Simona Halep (6/1 to win US Open) has suffered an injury scare ahead of the US Open after revealing she has an issue with her Achilles and needs to take some rest.

With just a week to go before the final Grand Slam event of 2018, the world number one has been forced to pull out of the Connecticut Open, much to her disappointment.

Halep has issued a statement apologising to her fans that may have already bought tickets hoping to see her this week, but says the decision is the right one.

The Romanian had accepted a wildcard to compete in her third straight tournament on the North American hard courts after a title run in Montreal and a runner-up finish in Cincinnati, but the heavy schedule appears to have taken its toll.

Halep has cited an issue with her right Achilles as the problem, and will be hoping rest will do the trick ahead of the US Open starting at Flushing Meadows on Monday.

“I really wanted to play it and I saw that many fans bought tickets to see me here,” she said in a statement. “But I feel very sore with my Achilles, and I need some rest.

“I had so many matches in the last two weeks, so it’s tough. See you next year, and all the best.”

Halep’s withdrawal is far from ideal but will give her the best chance possible of starting the tournament injury free.

Serena Williams is 5/1 favourite to win the US Open with Betfred and may be aided by a less than fully fit Halep taking to the court.
