Carlos Alcaraz came from a set down to beat Lorenzo Musetti and win the Monte Carlo Masters for the first time.
The four-time major champion produced some superb shots to overcome the Italian 3-6 6-1 6-0 on the clay.
It was a competitive match for a set and a half before Musetti, bidding for the biggest prize of his career, began to struggle with a leg injury.
The success was a sixth ATP Masters 1000 trophy for Alcaraz – his first since Indian Wells last year – and an 18th title overall.
It also gives the 21-year-old a confidence boost before he defends his French Open title in May.
“It’s been a really difficult week with a lot of difficult situations,” Alcaraz said.
“I’m really proud of my myself how I’ve dealt with everything. It’s been a really difficult month for me on the court and outside.
“Coming here and seeing how the whole hard work has paid off, I’m really happy.”
