World number one Andy Murray will miss next week’s ATP Masters Series event in Cincinnati with a nagging hip injury that also forced him out of this week’s Montreal event.  The move brings into question Murray’s status for the US Open, which starts August 28 in New York, and even if he is able to play, it remains to be seen how well he can perform after missing the two major hardcourt warm-up events for the Flushing Meadows fortnight.
“Unfortunately I won’t be playing in Cincinnati as I continue my recovery,” Murray said. “I always enjoy playing there and I look forward to returning next year. I’m continuing to work hard on the court with the aim of being in New York.”
The 30-year-old Scotsman, who has topped the rankings since last November, could be overtaken this week by French Open champion Rafael Nadal if the Spaniard reaches this week’s Montreal semi-finals. Nadal will be the number one seed next week in Cincinnati no matter how he fares in Canada this week.
It will be the first time since 2010 that Nadal, who won at Cincinnati in 2010, has been top seed there.
Wimbledon and Australian Open winner Roger Federer will be the second seed. He has won seven Cincinnati titles, including crowns in each of his past two appearances there in 2014 and 2015. This marks the first year since 2009 that Nadal and Federer are the two top seeds in Cincinnati.

Cilic, Querrey join Laver Cup teams
World number six Marin Cilic and 20th-ranked Sam Querrey have joined the teams for September’s inaugural Laver Cup in Prague, the organisers said.  
The 28-year-old Cilic, the 2014 US Open champion, will join Team Europe led by Swedish legend Bjorn Borg and also comprising Roger Federer, Rafael Nadal and Dominic Thiem.
“I know how well Roger (Federer) is playing this season so it will be nice to be on the same team in Prague,” Cilic said. “To be representing Team Europe is a huge honour for me.”
The 29-year-old Querrey will join Milos Raonic, Jack Sock and John Isner on Team World, captained by John McEnroe.
Borg and McEnroe have yet to announce two captain’s picks to complete their six-member teams for the new tournament to be played in Prague’s O2 Arena on September 22-24.
Named after Rod Laver, the last man to achieve the calendar Grand Slam in 1969, the Laver Cup will be held every year except in an Olympic season, with four matches each day — three in singles, one in doubles.
