Mariano Puerta has a competitive career record of 128–118 across 246 matches (52.0%). The record shows a player capable of competing at Tour level, though there is clear room to push the win rate higher. Claimed 3 titles: Palermo, Bogota, Casablanca.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Mariano Puerta is 15–18 (45.5%) across 33 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): Mariano Puerta is 16–21 (43.2%) across 37 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the calendar.
10 finals reached — won 3, lost 7 (30% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 16 semifinals. 24 quarterfinals.
vs. Top 10: 7–15 (31.8%, 22 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: 19–20 (48.7%); best-of-three: 109–98 (52.7%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Dominant season: 2000 — 40–21 (65.6%) from 61 matches. That year represents a level of dominance that sets the ceiling for what Mariano Puerta can produce.
