Andy Murray has shaken off the abdominal injury which threatened his participation at Wimbledon, the former world number one said on Saturday before declaring that there was still a lot of "good tennis" left in him. Murray, who won the grasscourt Grand Slam in 2013 and 2016, sustained the injury during his Stuttgart Open final defeat by Italian Matteo Berrettini earlier this month, after impressive wins over Stefanos Tsitsipas and Nick Kyrgios. The problem forced Murray, ranked 51st, to skip the Queen's Club event with doubts over his participation at Wimbledon but the Scot said things had improved since.
