Jack Pinnington Jones is enjoying the best run of his career as the Briton reached his first ATP Tour-level quarter-final at the Dallas Open in Texas.
The 22-year-old, who began the week ranked 181st in the world, has gone from qualifying to beating Italy’s rising star Flavio Cobolli for his first top-20 win, and then the USA’s Eliot Spizzirri, who recently took a set off Jannik Sinner in the third round of the Australian Open.
