“I always warned him about these issues, but he didn’t fix those mistakes…” said Jarren Duran, the Red Sox All-Star. Just days after Alex Cora was fired, the American player pointed out five mistakes in the team’s development plan and tactical errors during his time as coach. Duran also said that he and the team director repeatedly objected to Cora’s hasty decisions, but the Puerto Rican coach ignored these warnings. According to him, this negatively impacted the team’s performance, leading to unsatisfactory results.
Boston Red Sox All-Star outfielder Jarren Duran has publicly expressed his long-held frustrations with former manager Alex Cora, revealing in detail how ignored advice led to the team’s recent struggles just days after Cora’s firing. The 28-year-old star, who has established himself as one of the premier players in Major League Baseball with his blend of speed, power, and elite defense, chose this moment to shed light on internal issues that he believes were pivotal in the club’s inability to achieve success in recent seasons.
Speaking to media members gathered at Fenway Park, Duran made it clear that his comments were not born out of spite but from a desire to see the organization he has called home since 2022 thrive once again. “I always warned him about these issues, but he didn’t fix those mistakes,” Duran said, referring to Cora, who was let go earlier this week after what many considered a lackluster start to the 2026 campaign.
The decision to part ways with the 49-year-old manager came after the Red Sox posted a disappointing 8-15 record in the first month, prompting ownership to seek a change in leadership.
Duran went on to elaborate on the five mistakes he had identified in the team’s development plan and the tactical errors that plagued Cora’s time at the helm. These insights, he noted, were shared not only by him but also by the team’s director, who oversees much of the player personnel and strategic planning. Despite multiple meetings and presentations backed by statistics and player testimonials, Cora remained steadfast in his approach, a stance that Duran says ultimately hurt the team’s competitiveness in the tough American League East division.
The first mistake Duran highlighted was the flawed development plan for emerging talent. He pointed out that the organization had invested millions in scouting and signing young players, yet the pathway from minors to majors was mismanaged. Prospects were often promoted based on hype rather than readiness, leading to cases where players like top prospect Roman Anthony struggled with the mental and physical demands of big-league play right from the start. “These kids come up with huge expectations, but without proper grooming, they falter.
We saw it with several guys last year who could have been stars if given more time,” Duran explained, adding that this approach wasted potential and contributed to the team’s inconsistent offense.
Secondly, Duran criticized the tactical errors in bullpen management and pitching changes. He described instances where Cora would make impulsive decisions during games, such as bringing in a reliever who was not warmed up properly or sticking with a starter who was clearly fatigued. This led to blown leads and extra-inning losses that piled up over the course of the 2025 season. The bullpen, once a strength, became a liability as arms were taxed beyond their limits without strategic rest periods incorporated into the plan.
The third mistake involved the construction of daily lineups and the utilization of platoon advantages. Duran noted that the batting order often seemed arbitrary, not taking into account lefty-righty matchups or the opposing pitcher’s tendencies, which are readily available through advanced scouting reports. “We had guys who could exploit certain pitchers, but they were batting in spots that didn’t maximize their strengths. It was baffling,” he said. This extended to defensive positioning, where the team continued to employ shifts that data showed were ineffective against particular hitters, allowing cheap hits that turned into big innings for opponents.
Fourth, there were errors in the broader development strategy, particularly in how the team integrated new acquisitions and managed veteran players. Hasty decisions, such as trading away pieces that could have provided stability or failing to address clubhouse dynamics, created a lack of cohesion. Duran mentioned that he and the director had proposed alternative roster constructions that could have bolstered the team for a playoff push, but these suggestions were overlooked in favor of Cora’s vision.
The fifth and perhaps most telling mistake was the dismissal of collaborative decision-making. Duran recounted how warnings about potential pitfalls, including the risk of player burnout from excessive travel or poor workload distribution, were ignored. “The Puerto Rican coach had his way of doing things, and he didn’t see the value in adapting based on our feedback. It created a divide that affected everyone from the starting lineup to the bench,” he stated.
This lack of adaptability, Duran believes, was a root cause of the unsatisfactory results, including missing the playoffs in 2024 and 2025 despite having a talented roster on paper.
The impact of these unheeded warnings was profound, according to Duran. The team’s performance suffered as players lost confidence in the leadership, leading to mental errors on the field and a dip in overall morale. What could have been a contending squad instead became one that underachieved, watching from the sidelines as other teams advanced in the postseason. Fans, who had high hopes after the 2018 glory days, expressed their disappointment through declining attendance and vocal criticism on social media platforms.
With Cora now out, the Red Sox are in the process of interviewing candidates for the managerial vacancy. Names like former Cleveland Guardians manager Terry Francona, who has a proven track record of player development, and internal options such as hitting coach Peter Fatse have been floated. The organization has emphasized a commitment to a more inclusive and data-informed approach moving forward, which aligns with many of the points Duran raised.
The firing has also raised questions about the future of other coaching staff members, with some expected to be retained for continuity while others may be let go to bring in fresh perspectives aligned with the new direction. This overhaul comes at a time when the Red Sox are also dealing with contract negotiations for key players and the ongoing challenge of competing in a division stacked with talent.
Duran himself remains a bright spot for the franchise. Entering his prime, the California native has been instrumental in the early 2026 season, providing highlight-reel plays and timely hitting that have kept the team in games despite the off-field drama. His willingness to speak truth to power has earned him respect from peers across the league, with some calling him a future captain in the making.
As the dust settles on this latest chapter in Red Sox history, the focus shifts to rebuilding and learning from the past. The five mistakes outlined by Duran offer a clear roadmap for the new regime: prioritize proper player development, refine tactical execution with input from all stakeholders, optimize lineups and defenses with analytics, make thoughtful roster decisions, and foster open communication. If implemented effectively, these changes could propel the Red Sox back to relevance in a division that demands excellence.
For now, the baseball world watches closely to see if the warnings that went unheeded for so long will finally lead to positive transformation in Boston. Jarren Duran, having done his part by voicing concerns that others may have kept private, can only hope that the next chapter brings the success the team and its fans deserve.
