ATP rankings update: Indian Wells champion Carlos Alcaraz dethrones Novak Djokovic as World No. 1, Rafael Nadal exits top 10 after 912 weeks

Carlos Alcaraz has reclaimed the World No. 1 spot from Novak Djokovic in this week's ATP rankings. The teenager's triumph at the Indian Wells Masters over the weekend helped him reach the summit once again.

Alcaraz will now remain at the top of the rankings, at least until the end of the Miami Open, where he's the defending champion. If he successfully defends his title, he'll continue his reign until the end of the Monte-Carlo Masters.

From that point on, it'll be a regular battle between Alcaraz and Djokovic for the No. 1 ranking. Both are defending almost the same number of points until the end of Wimbledon - 1870 for the Spaniard and 1880 for the Serb.

Following Djokovic at No. 2 are Stefanos Tsitsipas and Casper Ruud at No. 3 and No. 4, respectively. Alcaraz snapped Daniil Medvedev's 19-match winning streak by defeating him in the Indian Wells final.

Nevertheless, the Russian moved up a spot to No. 5. Felix Auger-Aliassime rose by four places to No. 6, with Andrey Rublev (No. 7) and Holger Rune (No. 8) following him.

Hubert Hurkacz moved up by two places to return to the top 10 at No. 9. Taylor Fritz's title defense at the Indian Wells Masters ended in the quarterfinals. The American slipped by five places to No. 10 this week.

Rafael Nadal's record stay in the top 10 of the ATP rankings concludes at 912 weeks

Rafael Nadal exited the top 10 of the ATP rankings after 18 years.

Rafael Nadal first cracked the top 10 of the ATP rankings on April 24, 2005 as a teenager. After 22 Major titles and numerous other achievements, coupled with frequent injuries, he's finally set to depart the elite bracket after 912 weeks.

The Spaniard hasn't competed since his second-round exit from the Australian Open a couple of months ago. He picked up another injury during his loss to Mackenzie McDonald, which has kept him on the sidelines since.

Nadal's early exit from the season's first Grand Slam, where he was the defending champion, saw him drop a huge chunk of points. He then withdrew from the Mexican Open, which he won last year, losing another 500 points in the process.

The 36-year-old's absence from the recently concluded Indian Wells Masters saw him drop 600 points as he was a finalist there the previous year. Nadal slipped four places to No. 13 this week, ending a record stay in the top 10 that lasted for 18 years.
