⚖️ Analysis Summary
Public sentiment aligns with sharp money on Mariners, supporting follow over fade despite home underdog pricing value on spread. Game projects low-scoring due to T-Mobile Park factors (0.92 run suppressor), pitcher injuries depleting both rotations/bullpens, and recent defensive trends (Mariners 5 RA avg). Optimal play leans Mariners across markets with positive EV confirmed by sim and consensus.
