Spanish star Carlos Alcaraz, aged 18, on Monday became the youngest player to enter the top 10 of the ATP world rankings since his compatriot Rafael Nadal did so at the same age in 2005.
Alcaraz climbed two places to ninth in the world due to his straight-sets victory over Pablo Carreno Busta in the Barcelona Open final on Sunday. Britain's Cameron Norrie drops out of the top 10 to number 11.
It was the third title of the season for Alcaraz, having won the Miami Masters at the beginning of the month and the Rio tournament in February.
Carreno Busta swaps places with another Spaniard Roberto Bautista Agut, the former climbing to 18 and the latter moving down one spot to 19th.
Novak Djokovic still sits atop the standings despite losing to Russian Andrey Rublev in the final of the Belgrade Open. World number two Daniil Medvedev is out with a hernia problem.
Swiatek extends lead as world’s best
Iga Swiatek extended her lead as world number one on Monday, after winning a fourth straight title at the weekend in Stuttgart, while Paula Badosa climbed to second place in the WTA rankings.
Poland's Swiatek, who took over at the top from Ashleigh Barty after the Australian retired last month, thrashed Aryna Sabalenka in the final in Stuttgart on Sunday.
Spain's Badosa moved to a career-high mark by reaching the semi-finals in Germany before losing to Sabalenka.
Britain's Emma Raducanu edged closer to breaking into the top 10 after her run to the quarter-finals of the same event. AFP
