Zverev, Alcaraz Victorious in ATP Finals Openers; Musetti Replaces Djokovic

Tennis player Novak Djokovic had to pull out of a big tournament called the ATP Finals because his shoulder was hurting.

Another player, Lorenzo Musetti, is taking his place.

In the tournament, stars like Carlos Alcaraz and Alexander Zverev both won their first matches.

It was a special win for Alcaraz because it was the first time he's ever won his first match at this event.

Zverev, who has won before, also had a strong start.

It's also a big deal because for the first time, two Italian players, Musetti and Jannik Sinner, are playing in the ATP Finals together.

Alcaraz talked about how he's feeling motivated this year and is proud of his effort.

He said his match was tough, especially against a fast player like Alex de Minaur, but he's happy he won.

Zverev also shared his happiness about his comeback win in the tie-break.
