Yankees may tap MiLB manager as next bench coach with eye on Boone’s job

NEW YORK — The New York Yankees may be looking closer to home than anyone expected for their next major coaching move.

A surprise name has emerged from within the organization’s ranks. This person has earned rare recognition from peers across baseball. And the timing could not be more significant given the current state of the Yankees coaching staff.

The development comes as multiple coaching positions remain in flux following another disappointing postseason. Yankees’ bench coach Brad Ausmus just saw his contract expire. The organization has already cut ties with two other coaches. What happens next could reshape the entire dugout structure.

An unexpected honor stirs calls

Someone just received an accolade that typically signals bigger things ahead in baseball. Baseball America’s annual survey of minor league managers revealed their choice for “Best Manager Prospect” in the International League. This recognition differs from simple “manager of the year” awards. It specifically identifies someone peers believe is ready for promotion to the major leagues.

The winner manages within the Yankees system. He has spent three years developing talent at Triple-A Scranton/Wilkes-Barre. League managers voted him most likely to succeed at the next level.

His name is Shelley Duncan.

Duncan’s candidacy gained attention after Baseball America published its annual survey of minor league managers, naming him the International League’s “Best Manager Prospect.” Unlike standard “Manager of the Year” honors, this recognition identifies coaches seen as ready to lead in the majors — not just successful at the minor league level.

Duncan’s win underscored his growing reputation within baseball circles.

His recognition signals readiness for advancement, separating him from longtime minor league managers who excel at that level but prefer to remain there. Fellow managers across the league view his three years in Scranton as preparation for a major league role.

As the Yankees assess their coaching structure, Duncan has emerged as a logical candidate. Ausmus, Boone’s bench coach for the last two seasons, could still return, but the organization is weighing whether it’s time for a younger, internal voice with player development experience.

Rising star in the Yankees system

Duncan’s rapid rise through the Yankees’ coaching ranks has drawn steady praise. The Baseball America survey, which polls managers across all minor league levels, has distinguished him as someone capable of translating his success to the big leagues.

His combination of leadership, player communication, and on-field results has made him a standout among peers. Since taking over in 2023, Duncan has built strong relationships with top prospects while earning a reputation for emphasizing fundamentals — an area the Yankees have struggled with in recent years.

The organization’s timing to potentially elevate him now feels deliberate. The bench coach position, traditionally seen as a training ground for future managers, could serve as Duncan’s path to a full-time big league role.

Baseball bloodlines and Yankees history

Duncan’s baseball background is well established. He is the son of Dave Duncan, the longtime pitching coach for the St. Louis Cardinals and one of the most respected coaching minds in MLB history. Working under Tony La Russa, the elder Duncan helped guide multiple championship teams, giving Shelley a firsthand understanding of what a winning culture looks like.

During his own playing career, Shelley Duncan made his major league debut with the Yankees in 2007 and quickly became a fan favorite. He hit seven home runs in 34 games that season, contributing to a late surge that helped New York secure the American League Wild Card berth. His big-league career spanned just 144 games, but his connection to the franchise — and its values — has endured.

Developing future Yankees talent

What strengthens Duncan’s case most is his direct impact on the Yankees’ next generation of players. Several of the team’s emerging young stars passed through his system before reaching the majors. Breakout pitcher Cam Schlittler and rising utility man Ben Rice both worked under Duncan at Scranton, while top prospect Spencer Jones flourished under his leadership in 2025.

“The Yankees, known for pointing to the past, could use someone who has worked so intimately with their future,” Sports Illustrated noted in a recent analysis.

This experience has given Duncan valuable familiarity with players who could soon form the core of the Yankees’ roster. His work in developing talent and reinforcing clubhouse accountability aligns perfectly with the organization’s philosophy of promoting from within.

The Boone question looms large

Manager Aaron Boone remains under contract through the 2027 season, but another early playoff exit has again raised questions about his long-term future. The Yankees fell to the Toronto Blue Jays in four games in the American League Division Series, marking the team’s eighth straight season without a World Series appearance.

Still, if the front office ever decides to make a managerial change, Duncan represents a ready-made candidate who already understands the system. His success developing players and his emphasis on fundamentals could directly address some of the consistency issues that have plagued the Yankees in recent years.

Yankees tradition of promoting from within

The Yankees have long been known for maintaining continuity across their coaching ranks. They often prefer promoting internal candidates who understand the team’s expectations and clubhouse culture. Duncan, who has spent three seasons managing within the organization and has previous experience as a player in pinstripes, fits that mold perfectly.

This tradition of “keeping bloodlines consistent,” as one analysis described it, has helped preserve the Yankees’ identity over time. Duncan’s deep familiarity with the club’s philosophy makes him a strong contender to continue that pattern.

Meanwhile, Ausmus has made it known he eventually hopes to manage again.

“Yes, but I’m really not concerned about that at all,” Ausmus said earlier this year when asked about returning to a managerial role. “I’m completely focused here. I really enjoy being here. Working for the New York Yankees is a different animal.”

Should Ausmus depart, Duncan could step into the role seamlessly, offering both developmental expertise and leadership continuity.

What comes next

The Yankees enter the offseason facing several coaching decisions. The team has already moved on from bullpen coach Mike Harkey and first base coach Travis Chapman, leaving additional vacancies to fill. Pitching coach Matt Blake and catching coordinator Tanner Swanson also hold club options for 2026.

Whether Duncan is promoted this winter remains uncertain, but there’s no doubt his profile has risen sharply within the organization. The Baseball America recognition validated his work and placed him firmly on the radar for a major league promotion.

For now, Duncan continues preparing for another season with Scranton/Wilkes-Barre, but his growing reputation and influence are hard to ignore. The Yankees have a long history of rewarding loyalty and success from within, and Duncan has checked every box.

In the coming weeks, the Yankees will finalize their staff for 2026. Whether Duncan joins Boone’s bench or remains in Triple-A for another season, his name is now firmly entrenched in the organization’s future — both as a top coaching prospect and as a potential successor to Boone in the Bronx.
