Best Win Percentage on Grass Court

At the top of the Open Era list for Best Win Percentage on Grass Court, the answer depends on the sample threshold: with a smaller but still meaningful modern sample, Carlos Alcaraz leads the category with 35-4 and 89.74%, while among long-career grass-court greats the benchmark remains Roger Federer at 192-29 and 86.88%. Alcaraz’s grass record is still a developing sample, but it is already extraordinary: he has quickly moved to the top of the table and already owns a grass-court win rate that sits above the established all-time names.

Behind Federer come John McEnroe at 121-20 and 85.82%, then Novak Djokovic at 130-22 and 85.53%.

Other historical grass-court greats near the top include Pete Sampras at 101-20 and 83.47%, Jimmy Connors at 185-38 and 82.96%, Boris Becker at 116-25 and 82.27%, and Bjorn Borg at 72-16 and 81.82%.

In this record, the key distinction is sample size: Alcaraz currently owns the highest percentage on grass with a smaller active-career sample, while Federer remains the all-time large-sample grass-court benchmark, combining elite efficiency with unmatched grass-court volume.
