What is today's free pick for Toronto Blue Jays vs Seattle Mariners?

The free public pick is SEA (Moneyline) at -158. Jays took Mariners last night, 2-0. Seattle Injury Parity Favors Home Moneyline

Why does the model favor SEA?

Both teams absorb ~20-point injury swings; Seattle's 45-44 record edges Toronto's 42-46 despite symmetric damage. Toronto's 6-3 recent run masks road splits: 18-21 away versus Seattle's 25-20 home at T-Mobile Park. Mariners' pitcher-friendly stadium (factor 97, HR 94) compounds Toronto's three-man rotation void with Berríos sidelined.

What could go wrong with the SEA pick?

Toronto's last 9 games show 6-3 record and +0.8 run differential, suggesting recent form could override venue disadvantage.

Is the Toronto Blue Jays vs Seattle Mariners prediction a guarantee?
