✍️ Match Preview
Pre-Match Analysis
O'Higgins and Union La Calera meet at Estadio El Teniente in Primera División, Regular Season - 5. This fixture gets under way on Sunday 25 April 2021 at 23:00 UTC.
Poisson Model
The Poisson distribution model projects O'Higgins 0.64 xG and Union La Calera 0.81 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: O'Higgins attack 0.686 / defence 0.900 | Union La Calera attack 0.847 / defence 1.055. League average goals — home 0.883 / away 1.057. O'Higgins's attack strength of 0.686 is below the league average — the 0.64 xG projection reflects a team that scores at a discount to the division norm. Data: 4 O'Higgins games / 4 Union La Calera games used (CurrentSeason).
Result probabilities: O'Higgins 23% | Draw 45% | Union La Calera 33%. Fair-value odds: O'Higgins 4.35 | Draw 2.22 | Union La Calera 3.03. The draw (45%) is the Poisson-preferred outcome — neither side is more likely to win than to draw, making draw-inclusive markets the most model-aligned approach.
Goals markets: Over 2.5 probability 18% | BTTS probability 30% | Total xG 1.45. Under 2.5 is the strongly backed market at 82% probability — total xG of 1.45 sits well below the 2.5 threshold. The model is projecting a tight, low-scoring match based on both sides' defensive quality. BTTS No has firm model support at 70% — O'Higgins's lower xG of 0.64 creates a meaningful probability of a scoring blank, which suppresses the BTTS Yes probability to 30%.
Picks & Verdict
The Poisson model's preferred outcome is the draw at 45% — neither side is more likely to win than to draw. Draw-inclusive markets are the most model-aligned approach. Home win at 23% and away win at 33% are close enough that backing either outright carries significant draw exposure.
On the goals line, Poisson's 1.45 combined xG gives a 18% probability to Under 2.5 — Poisson-only — limited corroboration.

📝 Match Report
How It Unfolded
O'Higgins beat Union La Calera 1-0 at Estadio El Teniente, Regular Season - 5, in the Primera División. The remainder of the report sets that outcome against the pre-match model, the markets and the teams' data profiles.
The Model vs The Result
The Poisson model went into this projecting O'Higgins 0.64 xG and Union La Calera 0.81 xG, a combined 1.45. The scoreboard read 1-0 for 1 actual goal. Union La Calera landed 0.8 under their projected return. Those figures were built on strength ratings of O'Higgins attack 0.69 / defence 0.90 against Union La Calera attack 0.85 / defence 1.05, drawn from 4/4 games (CurrentSeason).
On the result, the model split it O'Higgins 23% | Draw 45% | Union La Calera 33%, with the draw its most likely call at 45%. Instead the game produced a O'Higgins win, an outcome the model had rated at just 23% — a clear break from expectation and a genuine upset by the numbers.
Goals & Markets
The model rated Over 2.5 goals at 18%. The game delivered 1, so it stayed under — in line with the projection. Over 1.5 had been 46% and missed. On both teams to score, the model sat at 30% and the match did not — another call in the model's favour.
Verdict
Grading the result against the stored data, 2 of 3 pre-match signals came in: result (miss), Over 2.5 (hit), BTTS (hit). Partial vindication: some calls landed, others slipped.
