Tanner Rainey’s time with the Detroit Tigers organization is over. The right-hander elected free agency after the 2026 season, ending a two-year run that closed with an outright assignment to Triple-A Toledo.
Rainey’s move came after he was designated for assignment in late August, cleared waivers and finished the season with Toledo. For a player who had already been through the roster churn that comes with a late-season DFA, free agency was the final step that opened the door to a new team and formally ended his stay with the Tigers.
The timing makes sense because the season is now over, and roster decisions that were only temporary during the summer have become permanent. Detroit finished 76-86, fourth in the American League Central, and missed the playoffs, so the club’s offseason cleanup now includes players who were on the edge of the roster and no longer protected by an active assignment.
Rainey still gave Detroit a usable stretch in 2026. He appeared in six major league games for the Tigers, going 0-0 with a 3.86 ERA and six strikeouts, while also posting a 5-4 record, a 3.40 ERA and 67 strikeouts with Triple-A Toledo. That was a better finish than his 2025 season, when he logged a 0-1 record and an 11.17 ERA in 13 games split between the Pittsburgh Pirates and the Detroit Tigers.
That split matters because it explains the choice that followed. A pitcher can finish strong in Triple-A and still reach free agency if the team does not keep him on the active roster or on the 40-man path it controls, and Rainey’s outright to Toledo did not lock him in. Instead, it left him available, and once he elected free agency, Detroit lost the right to carry him forward automatically.
Where Rainey lands next is the question that now matters. He enters the market with 217 career MLB games, a 5-11 record, a 5.46 ERA and 253 strikeouts over nine seasons, and his next contract will show whether another club values the late-season depth he still offered in Triple-A Toledo.
