Byron Black has a competitive hard court record of 165–148 across 313 matches (52.7%). The record shows a player capable of competing here, though there is clear room to push the win rate higher. Claimed 2 titles on hard: Seoul, Chennai.

At Grand Slam level (Australian Open & US Open): Byron Black is 19–20 (48.7%) across 39 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Byron Black is 20–31 (39.2%) across 51 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole hard swing.

7 finals reached on hard — won 2, lost 5 (29% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 11 semifinals. 23 quarterfinals.

vs. Top 10 on hard: 7–23 (23.3%, 30 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: 44–31 (58.7%); best-of-three: 121–117 (50.8%). Slightly better in five-set matches on hard — a positive sign for the Slams specifically.

Peak season: 1998 — 23–15 (60.5%) from 38 matches. That year captures the ceiling of what Byron Black can do on hard when performing at their best and represents the standard to aim for.
