No. 1 Jannik Sinner has ramped up training ahead of Wimbledon title defense‎

Jannik Sinner said he's changed his physical workload after his French Open meltdown, when he felt ill and dizzy in a second-round loss. Sinner spoke Saturday — in English and Italian — at Wimbledon as he prepares to defend his singles title. With Carlos Alcaraz sidelined by a wrist injury, Sinner is the leading favorite — just like he was in Paris — to win at the grass-court major.
