Cameron Norrie was not the only opponent Carlos Alcaraz had to overcome in the Argentina Open final, as he battled feelings of guilt after not doing "the right things" to recover from injury.
Alcaraz made it one title from one tournament in 2023 as he overcame Norrie 6-3 7-5 in Buenos Aires on Sunday.
Last year's US Open champion dropped just one set through the tournament as he marked his return to action in style, with the 19-year-old having missed the Australian Open due to a hamstring issue.
Alcaraz had not featured since November, and the world number two admitted he did not feel his application during his extended break was always as good as it should have been.
"This trophy is special. During those four months I had a hard time and I didn't do the right things off the court, and I felt a bit guilty after the injury," Alcaraz said.
"Fighting against this is not easy. Coming here, my first tournament after four months, and winning the first tournament since the US Open is very special for me."
Alcaraz won seven games on the bounce to swing the final in his favour, and believes he hit peak performance during the match.
"I felt very comfortable playing the final," Alcaraz added.
"I knew that it was going to be really difficult. I started really focussed on what I had to do at the beginning, my game, my level.
"This is the level that I have to play in finals."
Alcaraz has already collected seven titles in his young career, with five of those coming on clay.
His idol and compatriot Rafael Nadal won 13 clay-court tournaments prior to turning 20.
Combined with Alcaraz's haul, that total of 18 betters the 13 managed by all other players combined on the ATP Tour in the 21st century before turning 20.
Alcaraz is now set to play in the Rio Open, where he is the reigning champion, this week.
