Roberto Bautista Agut has an impressive grass court record of 55–27 across 82 matches (67.1% — strong). A win rate of that calibre over 82 matches is a reliable indicator of genuine quality on this surface. Claimed 1 title on grass: 's-Hertogenbosch.

At Grand Slam level (Wimbledon): a positive 22–10 (68.8%) across 32 matches — a player who generally rises to the occasion at the Slams on grass.

2 finals reached on grass — won 1, lost 1 (solid 50% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on grass. 6 semifinals. 14 quarterfinals.

vs. Top 10 on grass: 5–11 (31.3%, 16 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: 22–10 (68.8%); best-of-three: 33–17 (66.0%). Slightly better in five-set matches on grass — a positive sign for the Slams specifically.

Best season: 2014 — 7–1 (87.5%) from 8 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
