World No.1 and six-time Grand Slam winner Carlos Alcaraz has been forced to give up a significant portion of his prize money due to a little-known rule in tennis.

Carlos Alcaraz has been forced to forfeit a jaw-dropping £1.8million in prize money due to a rule which penalises players for not participating in ATP Masters 1000 tournaments. Despite leading the Bonus Pool with an impressive 4,420 points, the 22-year-old's absence from certain competitions means he has had to forfeit half of his earnings .

Earlier this month, the Spanish tennis star wrapped up the most successful season of his career, finishing the year as world No.1 . He has competed in 11 finals and clinched eight titles, including two Grand Slams at the French Open (Roland Garros) and the US Open.
