At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Billy Martin has struggled at Grand Slam level: 14–23 (37.8%) in 37 matches. The best-of-five format and elite fields make this the toughest benchmark on Tour.
2 finals reached — won 1, lost 1 (solid 50% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 10 semifinals. 30 quarterfinals.
vs. Top 10: 6–33 (15.4%, 39 matches). Top 10 opponents have represented a clear ceiling; addressing that deficit is the single biggest lever for improving the overall record.
By format — best-of-five: 13–19 (40.6%); best-of-three: 131–156 (45.6%). Slightly stronger in three-set contests, though the five-set record is still respectable.
