Dividing winners by unforced errors and calculating this ratio per match, we can identify one area where Zwerev falls slightly short. His ratio is 0.79, meaning roughly 8 winners for every 10 unforced errors. Compared to all tennis players, this still ranks within the top 30, but Alcaraz and Sinner are slightly ahead, with ratios above 1—that is, more winners than errors.
