Guido Pella has a competitive career record of 128–151 across 279 matches (45.9%). The record shows a player capable of competing at Tour level, though there is clear room to push the win rate higher. Claimed 1 title: Sao Paulo.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Guido Pella is 23–32 (41.8%) across 55 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): Guido Pella is 20–31 (39.2%) across 51 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 1, lost 4 (20% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 10 semifinals. 23 quarterfinals.
vs. Top 10: 4–16 (20.0%, 20 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: 26–36 (41.9%); best-of-three: 102–115 (47.0%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Peak season: 2019 — 36–25 (59.0%) from 61 matches. That year captures the ceiling of what Guido Pella can do when performing at their best and represents the standard to aim for.
