For as much criticism as the lineup endured in 2023, the Astros ultimate downfall was primarily due to a sharp pitching regression. A staff that posted a 2.90 ERA and 3.28 FIP in 2022 — arguably the best in the spot with 26.5 wins — never clicked on all cylinders the following season, which led to a 3.94 ERA, 4.31 FIP, and only 15.2 wins. While there were a couple of personnel changes, the staff was mostly the same following Justin Verlander’s return at the trade deadline. Losing Luis García and Lance McCullers Jr. for most, if not all, of 2023 didn’t help matters, but there simply wasn’t a ton of turnover within the staff.
