Andy Murray is hoping to defend his Queen's Club title in June as a grass-court warmup for Wimbledon and the London Olympics.
Murray has won the Queen's tournament twice in the past three years, and is trying to become the first Briton since 1925 to lift the trophy for a third time.
Wimbledon begins a week after Queen's, which starts June 11. The Olympic tennis tournament will also be held at the All England Club.
Murray will not have to face second-ranked Rafael Nadal at Queen's this year after the Spaniard pulled out of the tournament, citing stringent British tax laws that could cause the player to lose money by playing the weeklong tournament.
