Tennis hot prospect Carlos Alcaraz faced one of the toughest games of his ATP tour on Wednesday. Unseeded American Tommy Paul spoiled the Canadian's debut by beating him 6-7 (4/7), 7-6 (9/7), and 6-3 at the Montreal Masters.
The unseeded American came from a set down to seal the second-round victory in three hours and 20 minutes. However, both produced some incredible exchanges throughout, with Alcaraz giving up after losing a match point.
Alcaraz came into the event with two prestige Masters 1000 titles from Miami and Madrid and held a 42-7 record this season.
But the 34th-ranked Paul claimed victory on a volley winner after holding off the Spaniard's charge from 5-2 down in the third set.
