The Philadelphia Phillies may be moving closer to bringing Don Mattingly back as manager for the 2027 MLB season, but the club’s offseason plans could play a major role in determining what happens next.

According to MLB.com reporter Todd Zolecki, Mattingly’s return appears to be a likely outcome, although the situation remains unresolved. The Phillies have not officially confirmed their decision, leaving supporters waiting for clarity after another disappointing postseason exit.

Mattingly took over from Rob Thomson on April 28, following Philadelphia’s disastrous 9-19 start to the 2026 campaign. The team responded impressively under his leadership, finishing the regular season with one of baseball’s strongest records over that stretch before falling to the Atlanta Braves in the National League Wild Card Series.

Now, the Phillies face two major questions: Will Mattingly return to the dugout, and will the organization make the roster changes necessary to give him a better chance of winning in 2027?

With Alex Cora reportedly no longer an option after declining the Phillies’ managerial opportunity, Mattingly’s position has become increasingly important to the club’s offseason planning.

WHY DON MATTINGLY’S RETURN IS BECOMING MORE LIKELY

When the Phillies dismissed Thomson in April, the team needed an experienced leader who could stabilize a struggling clubhouse and get the season back on track.

Mattingly stepped into that role and helped Philadelphia recover from its poor start. The Phillies played substantially better after the managerial change, demonstrating that the roster still had the ability to compete despite its early difficulties.

That turnaround strengthened the argument for keeping Mattingly.

He already understands the organization, knows the players and has experience managing teams through difficult stretches. Retaining him would also provide continuity at a time when the Phillies must evaluate their roster and decide how aggressively to reshape it.

However, the regular season’s improvement did not translate into postseason success.

Philadelphia was eliminated by Atlanta after losing the decisive third game of their Wild Card Series, extending a frustrating run of playoff disappointments.

The defeat raised questions about the team’s offensive consistency, bullpen reliability and ability to perform under postseason pressure.

Mattingly’s supporters can point to the recovery he engineered after April. Those questioning the team’s direction can argue that reaching the playoffs is not enough for a franchise with championship ambitions.

The Phillies must consider both sides before making their final decision.

ALEX CORA’S DECISION CHANGES THE MANAGERIAL LANDSCAPE

One of the biggest developments in Philadelphia’s managerial search was Alex Cora’s decision not to manage the team in 2027.

Cora had been a serious candidate when the Phillies dismissed Thomson. President of baseball operations Dave Dombrowski reportedly offered him the job in April, but Cora declined.

After the 2026 season, Cora again indicated that he did not intend to manage next year, according to reports published by MLB.com and Reuters.

That decision changes Philadelphia’s options.

Cora has a successful managerial history, including leading the Boston Red Sox to the 2018 World Series championship. His previous relationship with Dombrowski made a reunion an attractive possibility.

With that route reportedly closed for 2027, the Phillies would need to explore other candidates if they decide against retaining Mattingly.

Starting a new managerial search could introduce further uncertainty, particularly as the organization prepares for a critical offseason.

Mattingly, meanwhile, has already demonstrated that he can lead the current roster through a difficult regular season.

That familiarity could make continuity appealing, although the Phillies still need to determine whether he is the right person to oversee the next phase of the team’s development.

THE OFFSEASON COULD BE THE BIGGEST FACTOR IN MATTINGLY’S DECISION

The most intriguing part of this situation is the potential relationship between Mattingly’s future and the Phillies’ offseason strategy.

A manager’s decision to return is rarely determined by the job title alone. The roster available to him, the organization’s expectations, the coaching structure and the level of support from the front office can all influence the situation.

Philadelphia faces several important personnel decisions.

Alec Bohm and Luis Arraez are among the players approaching free agency, while the club must also evaluate its bullpen and determine whether changes are needed elsewhere on the roster.

The Phillies’ offensive decline and late-season struggles were major concerns during their playoff elimination. The organization must decide whether to retain much of the existing core or make more substantial changes.

If the Phillies pursue a clear plan to address those weaknesses, Mattingly could have a better idea of what the team expects to accomplish in 2027.

If the roster remains largely unchanged, however, the same questions could follow the club into another season.

That does not mean Mattingly will refuse to return if significant changes are not made. His intentions have not been established publicly, and the organization has not announced a final decision.

Nevertheless, the offseason will reveal a great deal about Philadelphia’s direction and the role it sees for its interim manager.

THE PHILLIES’ ROSTER NEEDS MORE THAN A MANAGERIAL DECISION

Philadelphia’s managerial situation cannot be separated from its broader roster problems.

The team entered 2026 with high expectations but struggled badly early in the season. Although Mattingly helped stabilize the club, familiar weaknesses resurfaced during the closing weeks.

The offense became inconsistent, while the bullpen struggled to provide reliable late-inning support.

Those problems became especially costly in the postseason, where small mistakes can quickly decide a series.

A managerial change can improve communication, establish clearer responsibilities and help a team regain confidence. However, it cannot automatically solve shortcomings in hitting, pitching depth or roster construction.

The Phillies therefore need to evaluate their personnel alongside their leadership.

That could mean improving the outfield, strengthening the bullpen, reassessing the infield or identifying players capable of delivering more consistent offensive production.

The front office must also determine which members of the current core remain central to its championship plans.

These decisions will shape the team Mattingly—or any other manager—would inherit next season.

COULD DON MATTINGLY BE THE RIGHT MANAGER FOR THE NEXT PHILLIES CHAPTER?

There is a strong argument for retaining a manager who has already worked with the team and helped it recover from a difficult start.

Mattingly has extensive experience from his previous managerial roles with the Los Angeles Dodgers and Miami Marlins. His background gives him familiarity with the demands of managing a major-league clubhouse over a full season.

Philadelphia’s players have also spoken positively about him.

Following the postseason elimination, several players expressed support for Mattingly and praised his handling of the team during a challenging period. J.T. Realmuto, in particular, publicly backed the idea of retaining him, although the final decision belongs to the organization.

That support matters because a manager’s relationship with the clubhouse can influence how effectively a team responds to adversity.

However, player support alone does not guarantee that retaining a manager is the right organizational decision.

The Phillies must consider whether Mattingly’s approach aligns with their plans for roster construction, player development and postseason preparation.

They also need to determine what changes are necessary to improve the team’s performance in high-pressure situations.

The decision should be based on more than the results of one stretch of games. It should reflect the organization’s broader assessment of its direction.

WHY THE 2027 SEASON COULD BE A TURNING POINT

The Phillies have reached the postseason repeatedly in recent years, but their latest elimination has intensified questions about whether the current roster can deliver a championship.

The team’s established stars remain important, yet the organization must also consider the effects of an aging core, inconsistent production and the need for greater depth.

That makes the upcoming offseason particularly significant.

Philadelphia could choose to make targeted additions while retaining most of its established players. Alternatively, it could pursue more substantial roster changes to address weaknesses that have persisted across multiple postseason runs.

Either approach would have implications for the next manager.

A team built around continuity may value a familiar leader who understands the current clubhouse. A more extensive rebuild or tactical reset could lead the front office to consider a different managerial profile.

Mattingly’s future is therefore connected to a much larger decision about how Philadelphia intends to compete.

The club needs to establish whether its priority is to make incremental improvements or reshape parts of the roster in pursuit of a stronger postseason performance.

MY TAKE: THE PHILLIES MUST GIVE THEIR NEXT MANAGER A CLEAR PLAN

The most important issue is not simply whether Mattingly returns. It is whether the Phillies can build a roster capable of achieving their championship ambitions.

Mattingly helped restore stability after a 9-19 start, and that accomplishment should be part of the evaluation.

At the same time, Philadelphia’s early playoff exit demonstrated that the team still has problems to solve.

Bringing Mattingly back without addressing the roster’s weaknesses would risk leaving the same questions unanswered. Hiring a different manager without improving the team’s personnel could produce a similar result.

The organization needs to approach these decisions together.

If Mattingly returns, he should have a clear understanding of the club’s expectations and how the front office intends to strengthen the roster. If Philadelphia chooses another manager, that person should receive the same clarity.

The Phillies have invested heavily in building a competitive team. Their next decisions must demonstrate how that investment will translate into better postseason results.

FINAL VERDICT: MATTINGLY’S FUTURE DEPENDS ON MORE THAN HIS REGULAR-SEASON RECORD

Don Mattingly appears to remain a leading candidate to manage the Philadelphia Phillies in 2027, particularly after Alex Cora declined the opportunity to take the job.

His work following Thomson’s dismissal gives the organization a strong reason to consider continuity. However, the Phillies’ postseason elimination and their unresolved roster issues mean the decision is not entirely straightforward.

The offseason could prove decisive.

Philadelphia must determine which players to retain, where to strengthen the roster and what leadership structure will best support its championship ambitions.

Until the organization makes an official announcement, Mattingly’s return remains a possibility rather than a confirmed outcome.
