Dusan Lajovic has found hard courts difficult, recording 85–129 across 214 matches (39.7%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

At Grand Slam level (Australian Open & US Open): Dusan Lajovic has struggled at Grand Slam level on hard: 13–22 (37.1%) in 35 matches. The best-of-five format and elite fields make this the toughest benchmark on this surface.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Dusan Lajovic is 24–36 (40.0%) across 60 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole hard swing.

6 quarterfinals on hard, 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.

vs. Top 10 on hard: 4–13 (23.5%, 17 matches). Top 10 opponents have represented a clear ceiling on hard; addressing that deficit is the single biggest lever for improving the overall record here.

By format on hard — best-of-five: 14–26 (35.0%); best-of-three: 71–103 (40.8%). Slightly stronger in three-set contests on hard, though the five-set record is still respectable.

Best season: 2017 — 10–11 (47.6%) from 21 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
