The Houston Astros have signed free agent first baseman Christian Walker to a $60 million contract, marking a significant addition to their roster. Walker, a three-time Gold Glove winner, spent the last eight seasons with the Arizona Diamondbacks and has consistently hit over 26 home runs in recent years.

This acquisition poses challenges for the Seattle Mariners, who had shown interest in Walker but were likely priced out. With Walker now in Houston, the Mariners must explore other options for bolstering their lineup, particularly at first base.
