Mackenzie McDonald has a competitive grass court record of 19–19 across 38 matches (50.0%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Wimbledon): Mackenzie McDonald is 4–6 (40.0%) across 10 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

5 quarterfinals on grass, 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 grass: 1–2 (33.3%, 3 matches). Top 10 opponents have represented a clear ceiling on grass; addressing that deficit is the single biggest lever for improving the overall record here.

By format on grass — best-of-five: 4–6 (40.0%); best-of-three: 15–13 (53.6%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on grass.

Best season: 2018 — 5–2 (71.4%) from 7 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
