Alcaraz has won three ITF Men's World Tennis Tour titles and four ATP Challenger Tour titles since turning professional in 2018.
ATP has him ranked as high as world No. 22 in singles, which he achieved on September 27, 2021, and he is currently the British No. 2 in singles.
His first title success came in July 2018, when he made it into the main draw of the German Open and won the tournament.
Amazingly, he won his first-ever match on tour - and that win came against an established name in Pablo Carreno Busta.
Busta participated in his first-ever grand slam tournament when he was a qualifier at the 2013 French Open.
His strongest shot is a heavy topspin forehand, which he uses to move opponents around the court. He can also use his forehand to produce clean winners.
His service game is also especially effective on clay; he can generate a nice kick on his serve that makes it harder to pick on red soil.
From the time he turned professional in 2009 to 2013, Delbonis won five ATP Challenger and Futures titles.
Karatsev won his first ATP singles title at the 2021 Dubai Open as a wildcard, defeating South African Lloyd Harris in the final.
The Italian has won five singles career titles so far, showcasing his prowess when handed an opportunity.
