Bill Bowrey has a competitive clay court record of 39–37 across 76 matches (51.3%). 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): a positive 3–2 (60.0%) across 5 matches — a player who generally rises to the occasion at the Slams on clay.

9 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: 8–10 (44.4%); best-of-three: 31–27 (53.4%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Best season: 1969 — 13–7 (65.0%) from 20 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
