Alcaraz vs Legends: Who are the champions with the most titles before age 23?

Carlos Alcaraz, at just 22 years old, is challenging history with numbers that only a small group of legends have managed to achieve.
Indeed, the Spaniard already has 23 titles in his young career, which is three fewer than Sweden's Wilander (26) and six fewer than former champions Becker and Sampras (29) at the same age.
The list doesn't stop there, as Lendl (33), McEnroe (35), Nadal (36), and Connors (39) all surpassed the 30-title mark. An impressive number, but still far from the record holder: Björn Borg with 46 trophies.
The legend with eleven Grand Slam titles, who had already won a Major (Roland Garros 1974) at 18, was historically precocious. At that time, he came back from a two-set deficit against Manuel Orantes to become the youngest player to triumph in Paris.
Afterward, he went on to win five Grand Slams before even turning 23.
