Wimbledon LIVE: Tennis scores as Raducanu beaten by qualifier Lulu Sun

While Carlos Alcaraz is in an almighty battle on Centre Court, Jannik Sinner is showing no signs of hanging about over on Court 1.

Having taken the first set 6-2 against 14th seed Ben Shelton, he breaks the American in the very first game of the second set. Shelton gets Sinner’s first service game to 30-30 in response but two huge serves from the Italian bail him out and he’s 2-0 to the good.

Ben Shelton thought he’d been broken in the third game of the match by Jannik Sinner and the players were heading back to their chairs when Shelton decided to challenge the line call on the seemingly successful.

Out on Court 1, men’s No 1 seed Jannik Sinner is in action against young American star Ben Shelton. Shelton may be the busiest man in SW19 currently, with each of his first three singles matches going to five sets and he’s been playing doubles as well.

The youngster is still a ball of energy though and will relish the chance to upset the world No 1. It’s on serve at 1-1 in the early going.
