World No. 9 Grigor Dimitrov has officially withdrawn from the CitiOpen tournament in Washington. Tournament officials revealed the news on Sunday evening.
Dimitrov, who is coming off a title win at Queen’s Club and a semi-final run at the Wimbledon Championships, withdrew from the event citing a sinus infection and the flu. The 23-year-old has made some fantastic strides in Grand Slam events, as he reached the quarter-final round of the Australian Open, as well as the semi-final round at SW19. He holds a 35-10 record so far this season.
The surging Bulgarian was the third seed at the tournament, which is the first in the US Open Series leading to the final Grand Slam of the season. Following the CitiOpen, players will take part in the Rogers Cup in Toronto/Montreal, the Cincinnati Masters, and potentially the Winston-Salem Open, which takes place the week before the US Open.
With Dimitrov’s absence, the top four seeds at the event at Tomas Berdych, Milos Raonic, Kei Nishikori and John Isner. Richard Gasquet is also expected to take part in the tournament.
The CitiOpen takes place July 28 – August 2 in Washington, D.C.
