3 clean sheets in 19 appearances (16% of games). Keeping that many behind a relegation-threatened side (20th of 20) — a side that concedes more — points to a busy, productive season between the posts.

Strengths

Ceiling. High potential at just 20 — room to grow into a bigger role.

Watch points

Game time. Only 47.9% of available minutes — needs a settled run to prove the level.

Outlook

Rated 50.1 overall — a solid contributor and squad regular. A rotation minutes keeper carrying the gloves this season. At 20 the trajectory points up — potential sits near its ceiling (98/100) and market value should climb as minutes and output follow. With this floor already at 20, the ceiling gets tested by a step up in level — one to track.

At 20, Heerkens sits on 12.6, still climbing toward its peak. The blue line is Heerkens's projected Rating — 50.1 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
