Clay Court Statistics Overview
John Isner holds a solid clay court record of 82–67 across 149 matches (55.0%). A winning majority across 149 matches shows consistent ability to get results on clay. Claimed 1 title on clay: Houston.
At Grand Slam level (Roland Garros): a positive 22–14 (61.1%) across 36 matches — a player who generally rises to the occasion at the Slams on clay.
ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): a positive 26–20 (56.5%) across 46 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on clay.

vs. Top 10 on clay: 5–16 (23.8%, 21 matches). Top 10 opponents have represented a clear ceiling on clay; addressing that deficit is the single biggest lever for improving the overall record here.
