Clean sheets

3.13 tackles, blocks & interceptions per 90 — moderate defensive volume, with 10 clean sheets across 33 appearances. Doing that for a lower-table side (14th of 20) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.

Strengths

  • Availability. On the pitch for 80.8% of available minutes — a dependable presence in the XI.

Watch points

  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 39.2, Sumiyoshi carries the 21st-highest potential of the centre-backs in the J1 League (top 33%), and he is posting that for a lower-table side (Shimizu S-pulse finished 14th of 20) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as moderate defensive volume (3.13 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).
