Nick Kyrgios is through to the second round of the ATP Cincinnati Masters event, after a gutsy straight-sets win over Belgian David Goffin.
Kyrgios completed the 6-2 6-3 win over the world number 13 in 66 minutes, serving 10 aces.
Both players struggled with injury and fitness in the Cincinnati heat.
Kyrgios was visibly struggling for fitness as he returns from the hip injury which derailed his Wimbledon campaign.
But it was the Belgian world number 13 who called for the trainer with a leg complaint after the first set.
Goffin pressed on but his injury allowed Kyrgios to take control of the match.
The 22-year-old will now face Ukrainian qualifier Alexandr Dolgopolov.
