Buster C. Mottram has an impressive hard court record of 44–23 across 67 matches (65.7% — strong). A win rate of that calibre over 67 matches is a reliable indicator of genuine quality on this surface. Claimed 1 title on hard: Johannesburg WCT.

At Grand Slam level (Australian Open & US Open): a positive 5–3 (62.5%) across 8 matches — a player who generally rises to the occasion at the Slams on hard.

2 finals reached on hard — won 1, lost 1 (solid 50% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on hard. 8 semifinals. 9 quarterfinals.

vs. Top 10 on hard: 4–6 (40.0%, 10 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall hard court profile.

By format on hard — best-of-five: 6–4 (60.0%); best-of-three: 38–19 (66.7%). Slightly stronger in three-set contests on hard, though the five-set record is still respectable.

Best season: 1975 — 6–1 (85.7%) from 7 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
