Stan Wawrinka has a competitive grass court record of 35–35 across 70 matches (50.0%). The record shows a player capable of competing here, though there is clear room to push the win rate higher. Stan Wawrinka has reached 1 final without yet claiming a title on grass — one of the finest margins in tennis.

At Grand Slam level (Wimbledon): Stan Wawrinka is 23–18 (56.1%) across 41 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

One final reached on grass, without converting it into a title. That final-round experience is valuable groundwork for going one step further next time. 2 semifinals. 4 quarterfinals.

vs. Top 10 on grass: 1–5 (16.7%, 6 matches). Top 10 opponents have represented a clear ceiling on grass; addressing that deficit is the single biggest lever for improving the overall record here.

By format on grass — best-of-five: 24–19 (55.8%); best-of-three: 11–16 (40.7%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 2014 — 7–2 (77.8%) from 9 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
