⚖️ Analysis Summary

Public and money both lean toward the Mariners as home favorites, aligning with the simulation’s modest win-probability edge and creating no strong fade signal. Sharp-leaning value appears on the Astros run-line due to cover frequency and on the Over, where both clubs’ recent offensive outbursts (Mariners averaging near 8 runs, combined scoring frequently clearing 7.5) point to a higher-scoring spring contest. Overall scoring outlook favors the Over given pace and early-season variance.
