Kei Nishikori holds a solid grass court record of 42–27 across 69 matches (60.9%). A winning majority across 69 matches shows consistent ability to get results on grass.

At Grand Slam level (Wimbledon): a positive 22–12 (64.7%) across 34 matches — a player who generally rises to the occasion at the Slams on grass.

3 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. 7 quarterfinals adds further depth to that picture.

vs. Top 10 on grass: 1–7 (12.5%, 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: 22–13 (62.9%); best-of-three: 20–14 (58.8%). Slightly better in five-set matches on grass — a positive sign for the Slams specifically.

Best season: 2015 — 4–1 (80.0%) from 5 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
