Taylor Fritz is still awaiting his first win over Carlos Alcaraz, and the American didn't hold back from snubbing the Spaniard once before during Wimbledon.

"There are always small details that can be improved," said his coach Juan Carlos Ferrero on the eve of the semifinal between Alcaraz and Fritz. "I won't reveal what these details are because I don't want to give any advantage to his opponents, but we are working to make some small adjustments to his game," he added.
