Even after losing the first two sets by 3-6, 3-6 scores, 22 year old Italian Jannik Sinner came back strongly
to win his first grand slam title of his career by winning the last three sets, against a much more well known
Daniil Medvedev.
Medvedev lost to Rafael Nadal two years back as well, so it will be a shock for him as well.

Congratulations and well done to him, he's young so this will probably not be his last grand slam victory. He has an exciting career ahead of him.

Yes and this adds an element of excitement to the world of tennis, which has been dominated by Rafael Nadal, Novak Djokovik and (before them) Roger Federer.
In between, we had Andy Murray and a few more, but these 3 (celebrated as GOAT- Greatest of All Times)have been very dominant.
