Clean sheets

0 tackles, blocks & interceptions per 90 — light defensive volume, with 2 clean sheets across 12 appearances. Behind a title-challenging side (2nd of 20) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.

Outlook

With a Rating of 26.5, Sekiguchi carries the 41st-highest potential of the centre-backs in the J2 League of 70 — though on just 12 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (0 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).

Value & potential by age

Market valueRating

Solid = now · dashed = projected

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~5), then tapers with age. At 28, Sekiguchi sits on 2.9, past its peak and easing. The blue line is Sekiguchi's projected Rating — 26.5 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.
