If someone other than Marketa Vondrousova is to win Wimbledon on Saturday, they will first have to figure out how to win a tennis match while putting themselves through the mental and physical misery of playing Marketa Vondrousova.
Each time Elina Svitolina returned to her seat she looked a little more perplexed, more drained. With each passing game the left-handed Vondrousova made herself increasingly awkward to face, putting comical spin on her backhand slice, picking obscure angles and covering the court so nimbly that there was no safe space for Svitolina to find, no easy way out.
