[5] Following the 2024 World Series, eight Astros, including Alex Bregman, Caleb Ferguson, Ben Gamel, Kendall Graveman, Jason Heyward, Yusei Kikuchi, Héctor Neris, and Justin Verlander each became eligible to elect free agency and did so.

Entering his final arbitration season, Urquidy appeared in 79 games and 70 starts for the Astros, going 27–16 wins–losses and 3.98 earned run average (ERA) over 405 innings pitched, and three additional World Series contests won.

[8] On December 13, 2024, the Astros completed one of the most significant trades in franchise history, sending three-time All-Star, Silver Slugger and Gold Glove Award winner Kyle Tucker to the Chicacgo Cubs for infielder Isaac Paredes, pitcher Hayden Wesneski, and third base prospect Cam Smith.

[9] Ten days later, the Astros signed free agent first baseman Christian Walker to 3-year, $60 million contract, winner of three consecutive Gold Glove Awards, and had slashed .250/.332/.481 over the prior three seasons.

The Astros conclude spring training with two exhibition contests against their Triple-A affiliate, Sugar Land Space Cowboys, on March 24 and 25, at Daikin Park.
