Canadian teenager Denis Shapovalov produced a powerful display of big-hitting to deny France’s Benoit Paire the perfect 29th birthday present with a 7-6 (7-5) 4-6 6-4 victory in the second round of the Madrid Open.
World No.43 Shapovalov struck 38 winners, including 18 on his forehand, to seal victory in just over two hours.

Coric was leading 5-2 in the second set when heavy rain interrupted play at Caja Magica, and after a 40 minute delay he returned to complete his 16th match win of the season.
