Home cooking: Carlos Alcaraz runs winning streak in Spain to 15 with Barcelona repeat

WATCH: Carlos Alcaraz went back-to-back in Barcelona by beating Stefanos Tsitsipas in Sunday's final.

There's nothing quite like home cooking for Carlos Alcaraz.

The Spanish teenager won his second straight title at the Barcelona Open Banc Sabadell on Sunday with a 6-3, 6-4 win over Stefanos Tsitsipas on Pista Rafael Nadal.

Alcaraz earned his ninth career title with the 79-minute triumph, successfully defending a title for the first time in his young career so far. He also improved to 10-1 in his career in Barcelona, and extended an unbeaten run in Spain's ATP tournaments to 15 matches. (He won the Masters 1000 in Madrid last year, too.)

"It is incredible," Alcaraz, who didn't drop a set in his five matches, said. "To feel this energy and lift the trophy in Barcelona in front of my family and friends, and most members of my team are here as well. Playing this level and to lift the trophy in front of them is a good feeling for me."

Alacaraz also improved to 4-0 in his career against Tsitsipas in victory, and denied the Greek a first-ever triumph in Barcelona with it. Tsitsipas has been runner-up in Barcelona three times in the last five years, and also lost to Alcaraz last year in the quarterfinals.

The Spaniard was the first player to lose serve in the match—he was broken at 1-1 in the first set—but was never broken again after that. In fact, he lost just six points in his other nine service games played in the final. He later won the last three games to wrap up the first set, and took the second-set lead for good with another break of Tsitsipas' serve at 2-2.

"Me and my team were talking before the match about staying relaxed,” Alcaraz said. “To want to play the tough moments. Staying relaxed is the most important part for me. To forget the mistakes, everything and be myself on court. Not to think about all the people watching, but just me, the court, the racquet and the final."

Nine titles as a teenager ranks Alcaraz sixth all-time in ATP history in titles won before turning 20. Nadal and Bjorn Borg each won 17, followed by Mats Wilander (14), Boris Becker (12) and Andre Agassi (10).
