Jimmy Connors has had a dominant career, posting 1274–283 across 1557 matches (81.8% — exceptional). Few players in the Open Era have sustained that level of dominance across a full career. With 109 titles, among the most prolific champions in the Open Era: Masters, Jacksonville, Roanoke, Queen's Club and 56 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Jimmy Connors has been outstanding at the Slams — 233–49 (82.6%) across 282 matches. Winning more than 7 in 10 Grand Slam matches is the benchmark of an all-time great.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): Jimmy Connors is 5–6 (45.5%) across 11 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the calendar.
159 finals reached — won 109, lost 50 (solid 69% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 235 semifinals. 273 quarterfinals.
vs. Top 10: 134–111 (54.7%, 245 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall career profile.
By format — best-of-five: 293–70 (80.7%); best-of-three: 981–213 (82.2%). Consistent regardless of format — a sign of a well-rounded game that holds up as matches develop.
Historic season: 1976 — 99–8 (92.5%) from 107 matches. A campaign of 99 wins in a single season is among the finest single-season records the Open Era has seen — the clearest benchmark of what is achievable at peak level.
Jimmy Connors assembled a historic 36-match winning streak — one of the longest in the Open Era. Sustaining that level across so many matches demands physical and mental consistency that very few players have matched.
