Jonesy's Verdict

Strong
Both teams to score – Yes Lost Strong lean Strong · High BTTS odds

The model assigns a 76.5 % chance that both sides will find the net, driven by San Diego's 2.5 xG and Philadelphia's 1.8 xG against vulnerable defenses.

Show the maths
San Diego's expected goals of 2.5 exceed the usual 2.0 threshold for a goal‑rich side, while Philadelphia's 1.8 expected goals indicate they are also likely to score. The defensive averages – 1.3 conceded at home for San Diego and 2.3 conceded away for Philadelphia – widen the gap between what each team is likely to score and what they will allow. Combining these offensive and defensive metrics yields a BTTS probability of 76.5 %, making the both‑teams‑to‑score market the most decisive read.
Pick 2 · Both Teams to Score
Both Teams to Score — Yes Lost 76.5% model probability

With San Diego averaging 2.5 expected goals and Philadelphia Union averaging 1.8, the model gives a 76.5% chance both teams find the net, ahead of the 23.5% it gives to at least one side being kept out.

Show the maths
BTTS probability is derived from each side's expected goals (San Diego 2.5, Philadelphia Union 1.8) run through the same Poisson goal-expectancy model used for the match result: 76.5% of simulated outcomes have both teams scoring at least once, versus 23.5% where at least one side is shut out.
Pick 3 · Total Goals
Over 2.5 Goals Won 80.1% model probability

Combined expected goals of 4.3 (San Diego 2.5 + Philadelphia Union 1.8) points to an open game, with the model giving Over 2.5 Goals a 80.1% chance against 19.9% for Under.

Show the maths
Total goals probability comes from the same Poisson model summing both teams' expected goals (San Diego 2.5 + Philadelphia Union 1.8 = 4.3 combined): 80.1% of simulated outcomes finish with 3 or more goals, versus 19.9% finishing with 2 or fewer.
Match Result Model

Our Poisson model, built from each side's real season scoring and conceding rates, has San Diego at 53.3%, the draw at 18.9%, and Philadelphia Union at 27.7% to win.

Most Likely Scoreline

The single most likely scoreline in our model is 2-1 at 7.6% — treat any single scoreline price with caution given how spread out the probability distribution is across a low-scoring match.
