Former British tennis star Andrew Castle believes that Jack Draper can upset Carlos Alcaraz at Wimbledon this summer.

Alcaraz is the hottest ticket in tennis after his blockbuster win over world No. 1 Jannik Sinner in the French Open final on Sunday, and the Spaniard will be hoping to make it three titles in a row at SW19 next month.

Draper was knocked out by Alexander Bublik in the fourth round at Roland-Garros but he made up another place in the ATP rankings, which leaves him a career-high No. 4.

And Castle thinks he has the momentum to go all the way at the All England Club.

“He’s had a great year,” the 61-year-old told BBC Radio 5 Live. “Jack can win Wimbledon this year. You can’t possibly get to four in the world and not consider yourself, in front of home fans, a possibility.

“Don’t forget he beat Alcaraz at Queen’s last year. Of course Carlos had been in Ibiza for four days partying like a wild animal, but so what? He’s beaten him and he’s capable of winning Wimbledon, for sure.”
