Detroit Tigers ace Justin Verlander has been placed on the 15-day injured list due to inflammation in his left hip, a move the organization describes as precautionary but one that underscores the challenges facing the reigning American League Cy Young Award winner as he enters his age-43 season. The Tigers activated the IL placement retroactive to April 1, effective immediately, and called up right-hander Keider Montero from Triple-A Toledo to take Verlander’s spot on the 26-man roster. The decision comes after Verlander’s rough first start of the season, in which he lasted just 3 2/3 innings, allowed six hits, two home runs, and five earned runs against the Arizona Diamondbacks, leaving questions about his durability for a team already navigating a litany of pitching injuries.
Why Verlander’s Hip Inflammation Matters for the Tigers’ Rotation Strategy
Verlander’s placement on the injured list is more than just a roster move—it’s a critical inflection point for a Tigers rotation that has been besieged by injuries since the start of the season. The 41-year-old right-hander, widely regarded as one of the greatest pitchers in MLB history, has been a cornerstone of Detroit’s pitching staff since returning from Tommy John surgery in 2022. His presence in the rotation was seen as both a nostalgic and practical asset, particularly after top prospect Reese Olson underwent shoulder surgery that will sideline him for the entire 2025 season. Verlander’s IL stint forces the Tigers to rely on unproven depth, including Montero, who has logged just 189 innings in two major league seasons but has shown flashes of potential as a starter.
The Precautionary Move: Verlander’s Comments and the Tigers’ Medical Assessment
Verlander, speaking to reporters including Chris McCosky of the Detroit News, described the inflammation as a "fairly minor" issue but acknowledged that the timing could not be worse. "It’s just difficult because I feel like it’s close to being able to just work through it," Verlander said. "But the timing is bad, the weather is bad and the schedule is bad. Everything worked against it, unfortunately." The Tigers’ decision to place him on the IL—retroactive to April 1—reflects a conservative approach by manager A.J. Hinch and the medical staff, who are prioritizing long-term health over short-term gains. With Verlander’s next start originally scheduled for Sunday against the St. Louis Cardinals, a homecoming in his first appearance at Comerica Park since August 2017, the IL placement ensures he won’t return prematurely.
Verlander’s Injury History: A Legacy of Durability and Recent Setbacks
Verlander’s career has been a testament to durability, but his recent seasons have been marred by a series of injuries that raise concerns about his future. After missing nearly two full seasons due to Tommy John surgery (2020–21), he has been placed on the IL five times in the last four seasons. In 2023, he missed five weeks with a teres major strain, followed by a pectoral muscle issue in 2025 that sidelined him for a month. The 2024 campaign was particularly brutal, as Verlander was limited to 90 1/3 innings due to shoulder inflammation and a lingering neck injury. Despite these setbacks, Verlander has still managed to log 579 2/3 innings from 2022 to 2025, a remarkable feat for any pitcher, let alone one in his early 40s.
Verlander’s 2024 Season: A Mixed Bag Amidst Injuries
Verlander’s 2024 season with the San Francisco Giants was defined by inconsistency but also by resilience. Despite injuries, he posted a 3.85 ERA over 152 innings, striking out 20.7% of batters while walking just 7.9%. These numbers were a step down from his Cy Young-winning 2022 season in Houston, where he went 18-4 with a 1.75 ERA, but they were enough to convince the Tigers to sign him to a one-year, $13 million contract in February 2025. The deal was seen as a win-win: a nostalgic return for Tigers fans and a practical solution to shore up a rotation decimated by Olson’s injury. Verlander’s ability to eat innings and provide veteran leadership was a key factor in Detroit’s decision to bring him back into the fold.
The Tigers’ Rotation Depth Crisis: Who Steps Up in Verlander’s Absence?
The Tigers’ rotation was already in a precarious position before Verlander’s IL stint. Reese Olson’s shoulder surgery has effectively ended his 2025 season before it began, while Troy Melton, a promising young starter, opened the season on the 60-day IL. Sawyer Gipson-Long, another rotation piece, is also sidelined with an oblique strain. These absences have forced the Tigers to rely on a patchwork of starters and prospects, including Montero, who has split his MLB career between starting and relieving. Montero’s performance as a starter (4.05 ERA in 144 1/3 innings) has been more reliable than his relief work (6.25 ERA in 44 2/3 innings), making him a logical choice to fill Verlander’s spot.
The Healthy Core: Skubal, Valdez, Mize, and Flaherty Provide Stability
Amid the chaos, the Tigers do have a silver lining: their top four starters—Tarik Skubal, Framber Valdez, Casey Mize, and Jack Flaherty—remain healthy. Skubal, the team’s ace, has been a consistent force since his breakout 2023 season, while Valdez, acquired in a blockbuster trade before the 2025 season, brings a Cy Young-caliber presence to the rotation. Mize and Flaherty, both former top prospects, have shown flashes of brilliance, though Flaherty is still recovering from Tommy John surgery in June 2024. Their health is crucial, as the Tigers will need them to anchor the rotation while Verlander and others recover. If the front four can stay on the field, Detroit has a fighting chance to weather the storm.
Keider Montero: The Temporary Solution or Future Rotation Staple?
Montero, 24, has been a serviceable swingman over the past two seasons but has yet to establish himself as a consistent major league starter. Drafted by the Houston Astros in 2019, Montero was part of the package that sent Justin Verlander to the Giants in 2024 before being flipped to Detroit in a separate deal. His track record includes a 4.57 ERA over 189 career innings, with a notable split between his starting (4.05 ERA) and relief (6.25 ERA) roles. If Montero can replicate his Triple-A performance—where he posted a 3.50 ERA in 2024—Detroit may have found a temporary answer to its rotation crisis. However, his ability to step into Verlander’s role on a permanent basis remains an open question, especially if the Tigers pursue trade deadline reinforcements.
The Broader Implications: How Injuries Are Shaping the Tigers’ Season
Verlander’s IL placement is more than just an individual setback—it reflects a growing trend in MLB where aging stars, even those with Hall of Fame resumes, are increasingly vulnerable to injuries in their later years. For the Tigers, the situation highlights the challenges of balancing short-term competitiveness with long-term rebuilding efforts. The organization invested heavily in Verlander’s return, but his inability to stay healthy has already forced Detroit to scramble for solutions. As the season progresses, the Tigers will need to decide whether to double down on veteran stability or accelerate their youth movement, particularly with prospects like Jackson Jobe (recovering from Tommy John) and Joey Wiemer potentially factoring into the mix.
