On July 31, 2025, the Detroit Tigers made a significant move at the MLB trade deadline, acquiring veteran reliever Paul Sewald from the Cleveland Guardians. In exchange, the Tigers sent cash considerations and a player to be named later to Cleveland. This trade was aimed at bolstering the Tigers’ bullpen for the stretch run and potential playoff contention. However, the transaction also marked the end of an era for a once-promising pitcher in Detroit. To make room for Sewald on the 40-man roster, the Tigers designated former first-round pick Matt Manning for assignment, signaling the franchise’s decision to move on from the 27-year-old.
Paul Sewald: A Calculated Gamble
Paul Sewald, a 35-year-old right-handed reliever, brings a wealth of experience to the Tigers’ bullpen. Over nine seasons in the majors, Sewald has accumulated a 4.11 ERA, 1.15 WHIP, and 86 saves across 391 2/3 innings. Known for his high whiff rates, particularly with his sweeper pitch, Sewald has demonstrated an ability to excel in high-leverage situations. According to The Detroit News, Sewald posted a 30% whiff rate over the last three seasons, and his sweeper generated a 37% whiff rate in limited action this year.
Despite these impressive numbers, Sewald’s acquisition comes with risks. He has battled shoulder injuries throughout the 2025 season, most recently being placed on the injured list on July 15 due to a moderate teres major strain. While the Guardians have not provided a definitive timeline for his return, the Tigers are optimistic about his availability in September. As Motor City Bengals noted, Sewald’s experience and strikeout potential could prove invaluable during the postseason if he regains full health.
Matt Manning: A Promising Career Derailed
Matt Manning’s designation for assignment marks a disappointing chapter in the Tigers’ history. Selected ninth overall in the 2016 MLB Draft, Manning was once heralded as a future ace for the franchise. Armed with a high-velocity fastball and a sharp curveball, Manning was a consensus top-100 prospect in 2017, 2020, and 2021. However, a series of injuries and inconsistent performance prevented him from realizing his potential.
Over parts of four seasons in the majors, Manning compiled an 11-15 record with a 4.43 ERA, 1.287 WHIP, and 178 strikeouts in 254 innings. While there were glimpses of his talent—such as his role in a combined no-hitter against the Blue Jays on July 8, 2023—these moments were overshadowed by extended stints on the injured list. According to Yardbarker, Manning’s struggles continued in 2025, where he posted a 6.04 ERA and 1.62 WHIP in 50 1/3 innings at Triple-A Toledo, failing to secure a call-up to the majors.
The Tigers’ Strategic Vision
Under the leadership of team president Scott Harris, the Tigers have adopted a forward-thinking approach to roster construction. The acquisitions of Paul Sewald and Rafael Montero in recent days exemplify this strategy. Both pitchers are considered low-risk, high-reward additions who can provide significant value during the playoff push. As The Detroit News highlighted, Harris has prioritized acquiring pitchers with swing-and-miss potential, a critical component for success in high-stakes games.
While Sewald’s injury history raises concerns, the Tigers are confident in their ability to rehabilitate him, as they have done with other pitchers like Luke Jackson. Additionally, the decision to move on from Matt Manning reflects a pragmatic approach. Despite his pedigree, Manning’s inability to adapt to a relief role and his declining performance made him expendable. The Tigers are now focused on maximizing their chances of success in the short term, even if it means parting ways with a once-promising talent.
What Lies Ahead for Manning?
Although Manning’s time with the Tigers appears to be over, his career is far from finished. At 27 years old, he still possesses the raw tools that made him a top prospect. As CBSSports reported, Manning’s designation for assignment opens the door for other teams to claim him off waivers. Given his pedigree and the ability to be optioned to the minors, it is likely that another organization will take a chance on him.
If unclaimed, Manning could remain in the Tigers’ system, potentially serving as depth for the Triple-A roster. However, it seems increasingly unlikely that he will don a Detroit uniform again. For Manning, this represents an opportunity for a fresh start and a chance to rebuild his career elsewhere.
As the MLB trade deadline passes, the Detroit Tigers’ roster moves reflect a balance of ambition and pragmatism. While Paul Sewald’s arrival brings hope for immediate improvement, Matt Manning’s departure serves as a reminder of the challenges and uncertainties inherent in player development.
