Robert Kendrick has found hard courts difficult, recording 29–54 across 83 matches (34.9%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

At Grand Slam level (Australian Open & US Open): Robert Kendrick has struggled at Grand Slam level on hard: 2–9 (18.2%) in 11 matches. The best-of-five format and elite fields make this the toughest benchmark on this surface.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Robert Kendrick is 4–7 (36.4%) across 11 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole hard swing.

2 semifinals on hard 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. 3 quarterfinals adds further depth to that picture.

vs. Top 10 on hard: 0–7 (0.0%, 7 matches). Top 10 opponents have represented a clear ceiling on hard; addressing that deficit is the single biggest lever for improving the overall record here.

By format on hard — best-of-five: 2–9 (18.2%); best-of-three: 27–45 (37.5%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on hard.

Best season: 2004 — 3–2 (60.0%) from 5 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
