Radek Stepanek holds a solid grass court record of 43–29 across 72 matches (59.7%). A winning majority across 72 matches shows consistent ability to get results on grass.

At Grand Slam level (Wimbledon): Radek Stepanek is 19–14 (57.6%) across 33 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

2 semifinals on grass without yet reaching a final — consistent deep runs that show the ability to string together wins across a full draw, with the step to the final still to come. 9 quarterfinals adds further depth to that picture.

vs. Top 10 on grass: 2–6 (25.0%, 8 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: 19–14 (57.6%); best-of-three: 24–15 (61.5%). Slightly stronger in three-set contests on grass, though the five-set record is still respectable.

Best season: 2014 — 5–2 (71.4%) from 7 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
