The same pattern holds if we exclude service points and evaluate only rallies where the return is in play. Carlos Alcaraz leads, with Sinner and Zwerev following within less than a 4% difference.
This makes sense. Zwerev regularly beats opponents ranked lower than him, whether in Masters events or Grand Slams, just like the other two. His problems arise when facing top-five players. However, statistically speaking, his game is quite close to being the best in the world.
