Both sides enter the tie on opposite recent notes – Prat recorded a 5‑1 victory over San Rafael away, while San Rafael’s last recorded league result was a 1‑5 loss at home to Prat. The symmetry in their scoring rates and the fresh head‑to‑head result set up a tightly contested encounter.

Robbo's Verdict

Lean
Prat to win Slight lean Lean · Home advantage

Prat’s recent 5‑1 triumph over San Rafael demonstrates a higher conversion rate, aligning with the model’s 37.1 % win probability for the home side.

Show the maths
The model assigns Prat an expected goal value of 1.35, identical to San Rafael’s. Converting those xG figures into win probabilities yields 37.1 % for Prat and 37.1 % for San Rafael, with a 25.8 % draw chance. The identical xG means the model sees no scoring advantage, but the recent 5‑1 result suggests Prat can exploit their chances better, nudging the pick toward a Prat win.
Pick 2 · Both Teams to Score
Both Teams to Score — Yes 54.9% model probability

With Prat averaging 1.35 expected goals and San Rafael averaging 1.35, the model gives a 54.9% chance both teams find the net, ahead of the 45.1% it gives to at least one side being kept out.

Show the maths
BTTS probability is derived from each side's expected goals (Prat 1.35, San Rafael 1.35) run through the same Poisson goal-expectancy model used for the match result: 54.9% of simulated outcomes have both teams scoring at least once, versus 45.1% where at least one side is shut out.
Pick 3 · Total Goals
Over 2.5 Goals 50.6% model probability

Combined expected goals of 2.7 (Prat 1.35 + San Rafael 1.35) points to an open game, with the model giving Over 2.5 Goals a 50.6% chance against 49.4% for Under.

Show the maths
Total goals probability comes from the same Poisson model summing both teams' expected goals (Prat 1.35 + San Rafael 1.35 = 2.7 combined): 50.6% of simulated outcomes finish with 3 or more goals, versus 49.4% finishing with 2 or fewer.
Match Result Model

Our Poisson model, built from each side's real season scoring and conceding rates, has Prat at 37.1%, the draw at 25.8%, and San Rafael at 37.1% to win.

Most Likely Scoreline

The single most likely scoreline in our model is 1-1 at 12.2% — treat any single scoreline price with caution given how spread out the probability distribution is across a low-scoring match.
