Carlos Alcaraz has provided a worrying update on his fitness ahead of his first Six Kings Slam match today in Saudi Arabia.
Alcaraz was given a bye to the semi-finals of tennis’s biggest-money exhibition event in Riyadh – where each player receives a $1.5m appearance fee and the winner earns $4.5m – and will face Taylor Fritz from 5.30pm BST today, after the American beat Alexander Zverev 6-3, 6-4 in just 59 minutes in the quarter-final on Wednesday.
