WASHINGTON, Aug. 21 (Xinhua) -- World No.1 Simona Halep will not compete in her third straight tournament on the North American hardcourts this week after announcing her withdrawal from the Connecticut Open on Monday.

The Romanian had accepted a wildcard to the Premier-level event on the campus of Yale University, but after a title run in Montreal and a runner-up finish in Cincinnati, she was forced to pull out of the tournament with a right Achilles injury.

"I really wanted to play it and I saw that many fans bought tickets to see me here, but I feel very sore with my Achilles, and I need some rest," she said in a statement released by the tournament.

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

Halep won the title in New Haven in 2013, but has not competed at the event since 2014.
