Returning Alcaraz giving full effort to US defense

Carlos Alcaraz, the No. 2 seed, is returning to competitive tennis at the US Open after being sidelined since April with a wrist injury that forced him to miss both the French Open and Wimbledon. The defending champion faces Russia's Roman Safiullin in his first-round match on Monday at Flushing Meadows. Alcaraz insists he is 'feeling great' and has not needed to alter his playing style, stating he will compete at 100% effort.
