Chas McCormick enjoyed a very good 2023 season with 22 home runs and a 133 wRC+. His sharp decline in power in 2024 is one of the reasons that the team’s overall power declined this season.
The Astros’ team ISO declined by almost 30 points, and the team power ranking declined from 8th to 15th. Meanwhile, McCormick’s ISO declined by an incredible 121 points between 2023 and 2024—a 60% decrease in power. Chas isn’t the only hitter responsible for the decline in team power—for instance, Kyle Tucker missed three months in 2024 due to injury, which undoubtedly affected the Astros’ home run totals.
