Player Prop #2: Jose Altuve (Astros) Over 0.5 Runs / +105 / Confidence 68% / Table-setter role plus home park factors and Royals missing key defenders/pitchers favor Altuve crossing the plate.
Player Prop #3: Salvador Perez (Royals) Under 1.5 Total Bases / -130 / Confidence 66% / Astros allowing 4.7 but still limiting extra-base damage in recent low-scoring affairs; Perez volume tempered by overall Royals offensive injuries.

⚖️ Analysis Summary

Public and money are aligned on the Astros across moneyline and spread with under money exceeding bets on the total, creating no strong fade signal. Mathematical edge favors Houston due to home field, Royals’ extensive injured list (multiple starters and relievers out), and Astros’ ability to grind low-scoring wins. Overall scoring outlook leans under given Astros’ 3.6 runs per game average in the last 10 and Royals’ missing offensive pieces limiting upside.
