Stan Wawrinka broke his racket during his three-sets loss to the American Sam Querrey in the ATP 500 of Queen's second round. And the Swiss player did it through his knee, with extreme easiness. Querrey prevailed by 7-5 6-7(3) 6-1 to advance into the quarter-finals where he faced the No. 1 seed Marin Cilic on Friday. Wawrinka will compete in Eastbourne next week prior to Wimbledon.
