Holder Carlos Alcaraz blew hot and cold on a blazing Monday at Wimbledon but the Spaniard survived a massive scare to beat dangerous Italian Fabio Fognini 7-5 6-7(5) 7-5 2-6 6-1 and reach the second round.

Alcaraz hopes to become the first player on the men's tour since Bjorn Borg to complete the French Open-Wimbledon double in consecutive years. Alcaraz is only the third defending Wimbledon champion all-time to be taken to five sets in the first round of the following year's Grand Slam.

The two-time defending champ eventually asserts himself in the last set to pick up a 7-5, 6-7 (5), 7-5, 2-6, 6-1 victory amid record-breaking Day 1 heat at the oldest Grand Slam tournament.
