Both teams enter the final day at 80-81, but Houston owns the head-to-head tiebreaker for the AL West title. Texas advances only if it beats Minnesota and Houston loses to Oakland; betting-market estimates put Houston’s division chances near 80%, against roughly 20% for Texas.
After removing sportsbook margins, representative betting lines imply a 62.3% chance of a Houston win and a 53.3% chance of a Texas win. Requiring both a Rangers win and an Astros loss yields a 20.1% Texas chance to advance.
Other estimates cited put Houston’s AL West chances between 75% and 80%: CBSSports at 75%, ESPN at 78% and FanDuel at 80%. The article says its sensitivity chart’s 15.3% Texas-favored area is not a playoff-probability estimate; it counts combinations of game probabilities equally.
