Grand slam champions Stan Wawrinka and Marin Cilic have joined the field for the Aegon Championships at Queen's Club this summer.
Wawrinka broke the stranglehold of the 'big four' of men's tennis by winning the Australian Open last year while Cilic's victory at the US Open in September was an even more stunning result.
Cilic, who won the Queen's title in 2012, and Wawrinka join Andy Murray, defending champion Grigor Dimitrov and Lleyton Hewitt in committing to the tournament, which begins on June 15.
