At Grand Slam level (Australian Open & US Open): Taro Daniel has struggled at Grand Slam level on hard: 5–16 (23.8%) in 21 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): Taro Daniel is 11–14 (44.0%) across 25 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole hard swing.

vs. Top 10 on hard: 1–7 (12.5%, 8 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: 7–20 (25.9%); best-of-three: 47–72 (39.5%). 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: 2019 — 6–7 (46.2%) from 13 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
