Hyeon Chung has a competitive clay court record of 17–14 across 31 matches (54.8%). 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): Hyeon Chung is 2–2 (50.0%) across 4 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

2 semifinals on clay without yet reaching a final — consistent deep runs that show the ability to string together wins across a full draw, with the step to the final still to come. 4 quarterfinals adds further depth to that picture.

vs. Top 10 on clay: 0–3 (0.0%, 3 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: 3–3 (50.0%); best-of-three: 14–11 (56.0%). Slightly stronger in three-set contests on clay, though the five-set record is still respectable.

Best season: 2017 — 10–5 (66.7%) from 15 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
