Thomaz Bellucci holds a solid clay court record of 128–102 across 230 matches (55.7%). A winning majority across 230 matches shows consistent ability to get results on clay. 4 titles on clay: Gstaad, Santiago, Geneva — a record that reflects consistent ability to close out tournaments on this surface.

At Grand Slam level (Roland Garros): Thomaz Bellucci is 8–10 (44.4%) across 18 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): Thomaz Bellucci is 14–18 (43.8%) across 32 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole clay swing.

7 finals reached on clay — won 4, lost 3 (solid 57% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on clay. 15 semifinals. 28 quarterfinals.

vs. Top 10 on clay: 6–13 (31.6%, 19 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.

By format on clay — best-of-five: 18–15 (54.5%); best-of-three: 110–87 (55.8%). Consistent regardless of format on clay — a sign of a well-rounded game that holds up as matches develop.

Peak season: 2010 — 21–10 (67.7%) from 31 matches. That year captures the ceiling of what Thomaz Bellucci can do on clay when performing at their best and represents the standard to aim for.
