​The departure of Don Mattingly from the Toronto Blue Jays coaching staff continues to be a topic of conversation as the 2026 season unfolds, especially given how Mattingly has helped spark an unlikely turning point for the Philadelphia Phillies. His success in Philadelphia has not only fueled speculation about his long-term plans but also prompted a former Blue Jays player to question whether Toronto underestimated the impact of losing one of baseball’s most respected veteran coaches. Former Blue Jays outfielder Kevin Pillar recently weighed in on Mattingly’s exit, suggesting that his departure could be contributing to the club’s ongoing struggles this season. On an episode of “Foul Territory,” Pillar wondered aloud whether Mattingly’s absence has had a bigger effect than many anticipated. “Is it the reason the Blue Jays aren’t playing well? Could it be some reason that they’re not playing as well, the fact that Don was there last year and he’s not there anymore?” Pillar asked during a recent segment. “Clearly, there’s a void that’s missing without Donnie Baseball there, and clearly something has changed in Philadelphia, because we’re talking about the same group of players… The team’s playing better, so there’s something magical about Donnie Baseball.”
Pillar spent seven seasons with Toronto, from 2013 to 2019, and remains one of the more recognizable veterans to come through the organization in the past decade. His comments come as Mattingly’s influence becomes increasingly evident in Philadelphia following the club’s managerial change. With the Phillies firmly in playoff contention heading into the All-Star break, interim manager Don Mattingly indicated he would be interested in leading the club full time. ESPN reported that since Rob Thomson was fired in April, Mattingly has spearheaded a remarkable turnaround for the Phillies over the past two months. At the time of Thomson’s dismissal, the Phillies were 9-19, tied with the New York Mets for MLB’s worst record.
Mattingly’s impact in Toronto was well documented, and now, with his new team riding a wave of success while his former club struggles, it’s become clear that his influence on the offense was a crucial factor. There’s little doubt that Blue Jays manager John Schneider would have preferred to keep Mattingly in the dugout. “Having Mattingly as bench coach was a dream for Blue Jays manager John Schneider,” Keegan Matheson wrote for MLB.com. “As a kid growing up in New Jersey, Schneider had Mattingly’s poster on his wall. The initial awe wore off, of course, and the two grew close, the veteran Mattingly helping the younger Schneider lead this organization back to the World Series.”
Whether Mattingly will ultimately land the Phillies’ managerial job for next season remains to be seen, but as Philadelphia continues its resurgence, the conversation surrounding his influence continues to grow. The discourse surrounding his departure from Toronto—whether it has had a larger impact than anticipated—has become part of a broader narrative about how coaching leadership can shape a franchise’s fortunes. As Philadelphia’s late-season turnaround unfolds, commentators will continue to dissect the role Mattingly has played, not only in the Phillies’ immediate success but also in the broader dialogue about what the Blue Jays might have missed without his steady presence in their dugout.
