The Houston Astros have finalized a three-year, $60 million contract with free-agent first baseman Christian Walker, pending a physical exam. This move likely signals the end of Alex Bregman's time with the team, as Walker is expected to take over first base, while Isaac Paredes may fill in at third base.

Walker, a three-time Gold Glove winner, brings both defensive prowess and power to the Astros' lineup, addressing a position that struggled last season. The team still faces challenges in their outfield and must find a new home for Bregman, who could attract interest from several teams.
