Alcaraz beat both Djokovic and Nadal to win his second Masters title in Madrid, but is yet to play either at a Grand Slam tournament despite getting to No. 1 after the US Open.

The Spaniard turned 19 on a Thursday, beat a GOAT on Friday, and then another GOAT on Saturday.

Meanwhile, 20-year-old American Ben Shelton makes his Top 100 debut on the year-end rankings following a three-week, three-title winning streak on the Challenger tour.

The 19-year-old world No. 1 is not letting injury deter his ambition.

The two-time major finalist moved to 2-0 in the Green Group after battling past the American, 6-3, 4-6, 7-6 (6), Tuesday night in Turin.

Alcaraz has a significant points lead over Nadal and Tsitsipas, but isn't playing the ATP Finals due to an abdominal injury—and both of them can pass him.

The world No. 1 was forced to retire from his Rolex Paris Masters quarterfinal; his withdrawal from means Taylor Fritz will play in Turin as the eighth qualifier.

One 19-year-old has been welcomed with open arms; the other’s reception been a little rockier. Now Alcaraz and Rune, stars of present and future, will face off in a Masters 1000 quarterfinal.

The final ATP Masters 1000 of 2022 will see world No. 1 Alcaraz in an electric draw featuring the remaining Big 3 titans and surging young talents like Félix Auger-Aliassime.

This might look like a lopsided matchup on paper, but the Canadian is playing some of the best tennis of his life right now.
