Leonardo Mayer has a competitive career record of 179–197 across 376 matches (47.6%). The record shows a player capable of competing at Tour level, though there is clear room to push the win rate higher. Claimed 2 titles: Hamburg.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Leonardo Mayer is 34–39 (46.6%) across 73 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): Leonardo Mayer is 26–30 (46.4%) across 56 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the calendar.
5 finals reached — won 2, lost 3 (40% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 8 semifinals. 27 quarterfinals.
vs. Top 10: 2–33 (5.7%, 35 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: 44–42 (51.2%); best-of-three: 135–155 (46.6%). Slightly better in five-set matches — a positive sign for Grand Slam campaigns specifically.
Peak season: 2014 — 28–20 (58.3%) from 48 matches. That year captures the ceiling of what Leonardo Mayer can do when performing at their best and represents the standard to aim for.
