Paris - Novak Djokovic reclaimed top spot in the ATP rankings released on Monday after winning his 22nd Grand Slam title at the Australian Open.
The 35-year-old Serbian rose four places to dislodge Spain's Carlos Alcaraz, who missed the tournament through injury and dropped to second.
Djokovic's 10th Australian Open title means he is world number one for the 374th week since July 2011.
Greece's Stefanos Tsitsipas, who lost to Djokovic in straight sets in Sunday's final in Melbourne, overtook Norwegian Casper Ruud in third place, matching a career-best ranking he first achieved in August 2021.
Andrey Rublev of Russia, dominated by Djokovic in the quarter-finals, climbed to a career-best position of fifth.
The shock elimination of Djokovic's long-time rival Rafael Nadal in the second round saw the Spaniard drop four places to sixth.
