H2H History

Grimsby hold the superior head-to-head record in this fixture, claiming 4 wins from 8 meetings. The hosts have won just 1 times in that span.

The 8 previous meetings have averaged 2.2 goals per game — a neutral rate that provides no strong lean on the goals market from the H2H alone. The most recent clash, on 18 Apr 2026, ended 1–4 with Grimsby winning.

It is worth noting that Grimsby have a superior record in this fixture despite their visitor status — 4 wins from 8 meetings. Home advantage alone is not a sufficient reason to dismiss that track record.

Trading

Gillingham half-time and goal-timing data (57 games, 28 at home): they score before half-time in 57% of fixtures in home games; when goalless at HT, a second-half goal follows 84% of the time; BTTS occurs in 57% of their matches (home games); Over 2.5 goals lands in 46% of games (home games).

Grimsby half-time and goal-timing data (57 games, 28 at away): they score before half-time in 71% of fixtures in away games; when goalless at HT, a second-half goal follows 81% of the time; BTTS occurs in 54% of their matches (away games); Over 2.5 goals lands in 46% of games (away games).

BTTS rates are mixed from the trading data — Gillingham 53% versus Grimsby 51%; no strong lean in either direction. The over/under 2.5 picture is inconclusive from the in-play data (Gillingham 47% | Grimsby 47%).

Poisson Model

The Poisson distribution model projects Gillingham 1.26 xG and Grimsby 1.01 xG. These expected goals figures are the primary input: they feed a goal-probability matrix across all scoreline combinations to derive the result and market probabilities below. Underlying strength ratings: Gillingham attack 0.919 / defence 0.965 | Grimsby attack 1.023 / defence 1.006. League average goals — home 1.358 / away 1.019. Data: 57 Gillingham games / 57 Grimsby games used (CurrentSeason).

Result probabilities: Gillingham 40% | Draw 33% | Grimsby 27%. Fair-value odds: Gillingham 2.50 | Draw 3.03 | Grimsby 3.70. This is a low-confidence result — no outcome exceeds 45%. The draw at 33% is a primary outcome, not an afterthought.

Goals markets: Over 2.5 probability 39% | BTTS probability 48% | Total xG 2.26. Under 2.5 has a narrow probability edge at 61% — total xG of 2.26 is below the line but not decisively so. BTTS probability of 48% is moderate — neither team is projected to score with enough certainty to make Yes a clear standalone call.

Verdict

Grimsby lead the H2H ledger, but Gillingham carry stronger current form — do not let history alone dictate your assessment.

The Poisson model's primary lean is Gillingham at 40% — marginal model lean. Current-season form corroborates the Poisson lean — partial multi-source support. Draw probability of 33% warrants consideration of Double Chance or Draw No Bet on Gillingham if the outright odds are short.

Poisson projects 2.26 total expected goals, pointing to Under 2.5 at 39% probability — Poisson-only — limited corroboration conviction.

On the BTTS market, Poisson puts 48% on No. Form rates are neutral: Gillingham 30% | Grimsby 80%.
