WATCH: Alcaraz's lone Davis Cup defeat came against Félix Auger-Aliassime over the weekend.

Carlos Alcaraz is aiming for more big wins this season to consolidate his No. 1 position in the rankings.

The 19-year-old went straight to the Davis Cup playoffs following his title victory at the US Open, which also took him to the top spot in the ranking. But Alcaraz wasn't unnerved during his first appearance as the youngest No. 1 in ATP history.

"I heard [Daniil] Medvedev say that he felt the pressure, but I haven't felt it," he was quoted as saying, though adding that the cheering Spanish crowds in Valencia could have helped.

Nor is he backing off on his goals now he's a Grand Slam champion.

"I would like to win the [ATP Finals] Masters and the Davis Cup and try to finish No. 1. Now that I have reached here, I want to stay as long as possible," he said.

But first, he's taking a much-needed vacation at home in Spain. His breakthrough season has also included title victories in Rio, Miami, Barcelona and Madrid.

"I want to forget about tennis for a bit and enjoy myself," he said.

Spain has advanced in the Davis Cup playoffs. Alcaraz has also qualified for the ATP Finals.
