In another very short match at the Miami Open, Jannik Sinner retired against Cerundolo while trailing 1-4.
The Italian player was coming off of a brilliant outing against Nick Kyrgios but today things simply did not go his way.
It was blisters that was the cause of injury for Sinner who hands Cerundolo a first semi-final in his maiden ATP 1000. A brilliant milestone for the Argentinian.
