Jimmy Connors has been dominant on hard, posting 490–100 across 590 matches (83.1% — exceptional). Few players in the Open Era have sustained that level of dominance across a full career on hard. With 43 titles, among the most prolific hard court champions in the Open Era: Jacksonville, Columbus, Salt Lake City, Paramus and 23 more.

At Grand Slam level (Australian Open & US Open): Jimmy Connors has been outstanding — 67–11 (85.9%) across 78 matches. Winning more than 7 in 10 Grand Slam matches on hard is the benchmark of an all-time great on this surface.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Jimmy Connors is 3–4 (42.9%) across 7 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole hard swing.

55 finals reached on hard — converted 43 into titles (outstanding 78% conversion rate). Converting finals at that rate separates champions from contenders. 94 semifinals. 108 quarterfinals.

vs. Top 10 on hard: 43–43 (50.0%, 86 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: 95–17 (84.8%); best-of-three: 395–83 (82.6%). Slightly better in five-set matches on hard — a positive sign for the Slams specifically.

Peak season: 1974 — 24–0 (100.0%) from 24 matches. That year captures the ceiling of what Jimmy Connors can do on hard when performing at their best and represents the standard to aim for.

Historic: 46 consecutive wins on hard — one of the longest winning streaks on this surface in the Open Era. To sustain that level across so many matches demands physical and mental consistency that very few players in history have matched.
