Current Situation: Roster and Offseason Moves
The Astros retained their core but lost key bullpen arms like Hector Neris and Phil Maton. The addition of Josh Hader bolsters the back end, but depth remains a concern. Offensively, the team ranked 5th in wRC+ in 2024 and is expected to remain elite. The rotation, led by Framber Valdez and Cristian Javier, has question marks after Valdez's 3.45 ERA and Javier's inconsistency.
Key Factors Shaping the Season
Health and Aging Curve
Jose Altuve (34) and Justin Verlander (42) are critical. Altuve's 2024 was limited to 120 games; a full season could add 2-3 wins. Verlander's velocity decline (93.1 mph in 2024, down from 95.2 in 2022) is concerning. Our model assigns a 30% probability of a significant injury to a key player.
Division Competition
The Rangers and Mariners both improved. Texas added a top starter, while Seattle's young core matures. The Astros' division win probability is 45%, down from 55% last year.
Expert Consensus
FanGraphs projects 89 wins, while PECOTA has them at 88. Our blended model uses a 60/40 weight of PECOTA and ZiPS, yielding 90.2 wins. Most experts agree the Astros are a playoff team but not the clear favorite.
Historical Patterns
Since 2017, the Astros have averaged 96 wins. However, teams with a core age over 30 tend to decline by 3-5 wins annually. The 2025 squad has a weighted average age of 29.8, suggesting a slight regression.

Bull Case (Optimistic)
Full health from Altuve and Verlander, plus a breakout from Hunter Brown (3.80 ERA) leads to 95 wins. Yordan Alvarez stays healthy for 150 games, posting 45 HR. Astros win AL West by 5 games and reach ALCS.
Base Case (Most Likely)
90 wins, second in division. Offense top-5, rotation middle-of-pack. Bullpen holds but isn't elite. Wild Card berth, then a competitive divisional series loss.
Bear Case (Pessimistic)
Key injuries (e.g., Altuve or Valdez misses 6+ weeks) cause a 84-win season. Rotation depth exposed, bullpen overworked. Miss playoffs by 3 games.
