Chaim Bloom Reveals Valuable Lessons From Turbulent Red Sox Tenure

After nearly four years as the Boston Red Sox’s chief baseball officer from October 2019 to September 2023, Chaim Bloom is ready for the next chapter of his baseball career.

Bloom, 42, is in his first offseason as the St. Louis Cardinals’ new president of baseball operations after replacing John Mozeliak. It’s his first time running a team since the Red Sox dismissed him two years ago.

In an in-depth interview with MassLive’s Chris Cotillo at the GM meetings this week, Bloom reflected on his turbulent time in Boston and the valuable lessons he learned from it.

Three years after his firing, Chaim Bloom looks back at his Red Sox tenure, firing, the Mookie Betts trade and more.

“I feel the same way I felt about it when I was doing it,” Bloom said Tuesday at The Cosmopolitan of Las Vegas. “I loved it.” https://t.co/gr6LsH1vNV

“For me, it’s just really taking away from that (stint) my own understanding of the level of alignment that’s needed throughout an organization to point it toward success,” Bloom told Cotillo. “In this chair, you have to insist on that. You have to make sure, up and down the organization, that you’re setting that target really, really clearly for people about what needs to happen for the organization to succeed and that you’re holding people accountable to it.”

Bloom emphasized the importance of having a clear vision for an organization, getting everyone on board with it and keeping them rowing in the same direction.

“When you come into any organization, that creates change for everybody around you. It does take some work,” Bloom added. “Some of it’s going to happen naturally over time as relationships build. Some of it is work you really have to put in to make sure everybody really understands what the mission is and the roadmap you’ve charted to get there, and to be really clear and intentional about getting everybody on the same page and keeping the organization on target.”

Bloom was only 36 when the Red Sox hired him to replace Dave Dombrowski and lead the franchise into a new era. It was his first time running a baseball operations department and ended up being a big learning experience for him.

While Bloom struggled in Boston, overseeing three last-place teams in his four years at the helm, the Cardinals are hoping he’s learned from his mistakes and has more success the second time around.
