Why does the model favor HOU?

Houston won 7 of 9 with +1.7 run differential; Cleveland won 5 of 9 with +0.1, signaling momentum collapse. Astros own 59% head-to-head edge over 49 meetings, a structural advantage that compounds at neutral Minute Maid Park. Cleveland Guardians is 41-36 (0.532).

What could go wrong with the HOU pick?

Bazzana's 4-hit game and Cleveland's 22-19 road record suggest the Guardians' offense can travel, offsetting injury depth.
