Alcaraz emulated his childhood hero Rafael Nadal - a record 14-time champion at Roland Garros - by winning his fifth major at the exact same age of 22 years, one month and three days.
Sinner, meanwhile, is the youngest man to reach three consecutive Grand Slam singles finals since 14-time major winner Pete Sampras in 1994.
Such statistics offer a strong indication of the trajectory they both find themselves on.
So, where does their rivalry go from here?
The pair both have titles to defend at the two remaining slams in 2025 - Alcaraz at Wimbledon and Sinner at the US Open.
Alcaraz, who leads Sinner 20-19 in career titles, has reduced Sinner's lead at the top of the world rankings to 2,030 points.
But the reigning champion has 2,000 points to defend at Wimbledon, compared to just 400 for Sinner after his quarter-final exit last year.
"I'm sure he will learn from this match and come back stronger next time we face each other," Alcaraz added.
"I'm sure he's going to do his homework. I'm going to try to learn how I can be better [and] tactically hurt his game.
"I'm not going to beat him forever, that's obvious. So I have to keep learning from the matches I play against him."
