President of Baseball Operations
Chaim Bloom was officially introduced on September 30, 2025 as the new Cardinals President of Baseball Operations.
Bloom initially joined the Cardinals organization as an Advisor to the President of Baseball Operations in January 2024. At the conclusion of the 2024 season, it was announced that Bloom would become the team's President of Baseball Operations after the 2025 season, and that he had agreed to a five-year contract through 2030.
Since joining St. Louis, Bloom has revamped the organization’s Player Development and Performance departments, and added numerous staff from throughout the baseball industry into leadership, coaching, and front office roles while also empowering many returning staff in new positions. In addition, Bloom created a dedicated Pro Acquisition department, integrated new information sources, technology, and programming into organizational processes, and advanced communication and collaboration within baseball operations.
Prior to joining the Cardinals, Bloom served as the Boston Red Sox Chief Baseball Officer for four seasons (2020-23), where the Red Sox posted 92 wins in 2021 and reached the American League Championship Series. Under Bloom's direction, the Red Sox's farm system improved from No. 30 in 2019 to No. 10 in his final season. Baseball America ranked the Red Sox as the No. 1 minor league organization in 2025.
Bloom spent 15 years (2005-19) in the Tampa Bay Rays baseball operations department, including the final three as Senior Vice President, Baseball Operations. Over his tenure with the club, Bloom worked in nearly every area of the team’s baseball operation and was an integral part of both the Rays player development efforts and the team’s on-field performance at the Major League level.
Originally hired by the Rays as a baseball operations intern in 2005, Bloom joined the club on a full-time basis shortly after and was appointed Assistant Director, Minor League Operations in 2008. In that role, he gained a wealth of experience in all aspects of player development, including player evaluation, skill development, the integration of new technology and information sources, staffing, and overall philosophy.
Bloom later became Director, Baseball Operations for the Rays in November of 2011, and following the 2014 season, he was promoted to Vice President, Baseball Operations. In that role, his responsibilities included oversight of personnel, domestic and international player development, international scouting, contract and trade negotiations, salary arbitration, budgets, and strategic planning.
