Guillermo Canas holds a solid grass court record of 26–18 across 44 matches (59.1%). A winning majority across 44 matches shows consistent ability to get results on grass. Guillermo Canas has reached 1 final without yet claiming a title on grass — one of the finest margins in tennis.

At Grand Slam level (Wimbledon): Guillermo Canas is 9–9 (50.0%) across 18 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. 4 semifinals. 4 quarterfinals.

vs. Top 10 on grass: 1–3 (25.0%, 4 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: 9–9 (50.0%); best-of-three: 17–9 (65.4%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on grass.

Best season: 2001 — 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.
