Jack Sock has a competitive career record of 181–155 across 336 matches (53.9%). 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: Houston, Auckland, Paris Masters.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Jack Sock is 32–31 (50.8%) across 63 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): a positive 50–44 (53.2%) across 94 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
7 finals reached — won 3, lost 4 (43% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 16 semifinals. 35 quarterfinals.
vs. Top 10: 9–30 (23.1%, 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: 36–35 (50.7%); best-of-three: 145–120 (54.7%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Peak season: 2017 — 38–23 (62.3%) from 61 matches. That year captures the ceiling of what Jack Sock can do when performing at their best and represents the standard to aim for.
