Granillo made his Major League debut with the St. Louis Cardinals in 2025. Across 14 relief appearances for St. Louis, he posted a 4.71 ERA, tallying 18 strikeouts against seven walks over 21 innings. The Cardinals traded Granillo to the Nationals on February 10, 2026, in exchange for right-hander George Soriano. In Washington, Granillo appeared in eight games this season, recording a 9.64 ERA with three strikeouts and eight walks over 9 1/3 innings. Prior to the waiver claim, he had spent time with Triple-A Rochester before being designated for assignment on July 4.
The move gives the Tigers additional bullpen depth as they approach the stretch run of the season. Granillo has experience at the MLB level, with a light track record in the majors but potential as a left-on-left option or a middle-relief contributor depending on his development and organizational needs. He has faced a mix of hitters at both the majors and minor leagues, and his performance metrics in the high-minor and major leagues have shown both adaptability and room for improvement.
From a strategic standpoint, the Tigers’ decision to acquire Granillo via waivers signals a broader goal of adding versatile bullpen arms that can be deployed in varying roles. Teams often look for bullpen pieces who can bridge innings between starters and late-inning relievers, and Granillo’s profile suggests he could be utilized in multiple relief scenarios as he settles into Detroit’s pitching staff. His progress at Triple-A Toledo will be closely monitored, with the organization likely focusing on refining his command and breaking ball consistency to reduce walks and improve consistency against both right-handed and left-handed hitters.
Fans and analysts will be watching how Granillo adapts to the Tigers’ pitching philosophy and how much opportunity he receives to prove himself at the major league level. For Baltimore or New York-based scouts familiar with Granillo’s prior MLB stints, the weighting of his strikeout-to-walk ratio and his ability to pitch in higher-leverage situations will be key indicators of his trajectory with Detroit. If he responds well to the coaching staff and demonstrates improved control, Granillo could carve out a more regular roster role as the season progresses.
In summary, the Tigers added a right-handed reliever with major league experience by claiming Andre Granillo off waivers from Washington and designated him for assignment to Triple-A Toledo. This move aligns with Detroit’s aim to strengthen its bullpen depth as it competes for wins in a challenging schedule, while giving Granillo an opportunity to refine his game within the organization and possibly contribute at the MLB level in the future.
