Key Takeaways
  • • Jon Jay, 39-year-old former St. Louis Cardinals outfielder (2010-2015) and 2011 World Series champion, has been named to manager Oliver Marmol's coaching staff as outfield, baserunning, and quality control coach for the 2025 season.
  • • Jay transitions to the Cardinals coaching role after serving two seasons as first-base coach for the Miami Marlins under Skip Schumaker, a former Cardinals teammate and coach, demonstrating continuity in organizational relationships.
  • • The Cardinals simultaneously hired Brant Brown, 53, as hitting coach—replacing Turner Ward after the franchise missed playoffs for a second consecutive season with offensive deficiencies ranking 12th in NL runs (672), 12th in homers (165), and 13th in RBIs (639).
  • • Brown brings coaching experience from the Seattle Mariners (offensive coordinator and bench coach, fired May 2024), Los Angeles Dodgers (2018-2022 assistant hitting coach and strategist), and Miami Marlins (2023 head hitting coach under Schumaker), providing institutional knowledge across multiple organizations.
  • • Cardinals president of baseball operations John Mozeliak characterized Brown as bringing "a lot of energy" and a new strategic approach to hitting instruction that will serve as a "new voice for our hitters" following a minus-47 run differential season driven by offensive underperformance.
Summary
The St. Louis Cardinals announced dual coaching staff additions on Tuesday, hiring Jon Jay as outfield, baserunning, and quality control coach alongside Brant Brown as hitting coach for the 2025 season under manager Oliver Marmol. Jay, 39, returns to the franchise where he spent six seasons as a player from 2010 to 2015, culminating in participation on the 2011 World Series championship team. His appointment follows two seasons serving as first-base coach for the Miami Marlins, where he worked alongside Skip Schumaker—a former Cardinals teammate and coach who was then managing the Marlins.

Brown's hiring represents a strategic pivot in offensive coaching philosophy following two consecutive seasons of playoff misses. The 53-year-old departed the Seattle Mariners in May 2024 after the organization's slow offensive start, though his track record includes significant accomplishments: he served as assistant hitting coach and hitting strategist with the Los Angeles Dodgers from 2018 to 2022 and as head hitting coach for the Miami Marlins in 2023, when Schumaker's team made an unexpected playoff run that earned Schumaker National League Manager of the Year honors. Brown replaces Turner Ward, removed after the Cardinals' 83-79 season concluded with offensive metrics that ranked among baseball's weaker performances.

Cardinals president of baseball operations John Mozeliak emphasized that Brown's appointment signals a substantive change in offensive approach. "The way he thinks about hitting and approaches it, it's going to be a change from where we've been," Mozeliak stated, noting Brown's mentorship capacity for younger coaching staff. The 2024 Cardinals offense ranked 12th in the National League in runs scored (672), 12th in home runs (165), and 13th in RBIs (639), contributing to a minus-47 run differential that defined the season's competitive shortcomings. Mozeliak characterized Brown as bringing "a lot of energy" and positioning him as "a new voice for our hitters," indicating organizational expectations for tangible offensive improvement through revised instructional and strategic methodology.

The coaching announcements consolidate institutional experience within the organization, with both hires maintaining prior connections to either the Cardinals franchise or the Marlins coaching infrastructure where Schumaker's recent managerial success demonstrated offensive optimization potential.
