Tom Gullikson has a competitive clay court record of 28–31 across 59 matches (47.5%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Roland Garros): Tom Gullikson is 4–5 (44.4%) across 9 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

4 quarterfinals on clay, including one run to the semifinal — regularly reaching that stage is a solid baseline, with the next step being to break through to the final rounds more often.

By format on clay — best-of-five: 4–4 (50.0%); best-of-three: 24–27 (47.1%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Best season: 1977 — 11–11 (50.0%) from 22 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
