The teenager told reporters he was motivated by the soundtrack to the Rocky movie series and due to storms and disrupted schedules, the Miami Masters winner was forced to personify all his fighting qualities to lift the trophy aloft.
A three-set bout packed with tension and shot-making against Stefanos Tsitsipas set the tone. On Saturday the 18-year-old had to complete two matches and Alcaraz took it all in his stride, able to go 12 rounds, whatever the challenge in the ring.
First up, a near four-hour tussle with Alex de Minaur. The Spaniard saved two match points (one being a gobsmacking forehand pass, out of position, on the run and contorting his body to strike almost behind his body) to eventually prevail 6-7(4), 7-6(4), 6-4.
A few hours later and Alcaraz retuned to court to ping winners from here, there and everywhere going 6-3, 6-2 to topple his mentor and good friend Pablo Carreno Busta.
