While the MLB draft was grabbing everyone’s attention, the Tigers slipped in a small move of their own, claiming right-handed reliever Andre Granillo off waivers from the Nationals.
Detroit optioned Granillo to Triple-A, and the move also brings the Tigers’ 40-man roster to capacity. On paper, it’s a minor transaction buried in the middle of a major baseball event. But given the way the Tigers tend to operate, Granillo could still surface in the big leagues before long if injuries open a door or if Scott Harris decides he wants more from the bullpen later in the season.
Granillo has already logged 9 1/3 major league innings for Washington this year, and the results were rough: a 9.64 ERA. His last outing came on May 5, when he worked two innings and allowed four runs against the Twins. He was optioned the next day and then designated for assignment on July 4, setting up the Tigers’ claim.
There’s at least some pedigree here. Granillo was a 14th-round pick by the Cardinals in 2021 and ranked as St.
Louis’ No. 30 prospect in 2023 and No. 28 in 2024. He made his MLB debut in June 2025 and ended up throwing 21 innings between trips back to the minors, finishing with a 4.71 ERA.
St. Louis later dealt him to Washington in February for pitcher George Soriano.
The appeal for Detroit is obvious enough: Granillo was much better in Triple-A last year, posting a 1.29 ERA with 58 strikeouts in 42 innings in the Cardinals’ system. The production dipped after he got to Washington, where he recorded a 6.82 ERA in 31 2/3 innings.
So the Tigers took a shot. Maybe there’s something left to tap into. They’ve already gotten an unexpected bullpen success story this season in Jacob Waguespack, who didn’t carry the same prospect buzz Granillo once had.
Anyway, back to the draft.

Tigers Make A Surprising Outfield Move Fans Didnt See Coming
Detroit kept its outfield shuffle going by moving on from Trei Cruz and opening a roster spot for Brett Callahan, a prospect who has climbed quickly enough to force his way into the conversation. Cruz had a brief big league look in June and went hitless in five at-bats, a small sample, but one that left him without much runway as the Tigers continued sorting through options.
Callahans rise gives the club a new name to watch, especially for a player who was a 13th-round pick in 2023 and only reached Triple-A Toledo in June. This will be his first major league roster appearance, and while the Tigers are clearly betting on the upside, the move also leaves open the question of how quickly he can turn that opportunity into something lasting.

Tigers Return For Casey Mize May Already Offer Bullpen Help
The Tigers return for Casey Mize may not look like immediate major league help on paper, but it already has a path to the big club. Detroit added left-handers Kash Mayfield and Jackson Wolf in the deal, and while Mayfield remains a promising 2024 first-round pick who has yet to debut for the Tigers, the more practical short-term name is Wolf. He has now surfaced in Triple-A Toledo, giving the organization another arm to track as it sorts through pitching depth.
Wolf is not expected to jump straight into a major league rotation spot, but his fit could come in a different role if Detroit needs it. For a club that is always weighing innings, durability and bullpen flexibility, that kind of option matters even before the headline pieces of the trade are fully sorted out. Mayfield brings the higher ceiling, but Wolf may be the one who can help sooner, and the Tigers will keep watching how that assignment develops. [Read more 🡒]
Tigers Just Made Scott Harris Biggest Gamble Yet
The Tigers made their boldest move under Scott Harris by sending Tarik Skubal to the Los Angeles Dodgers for a package built around two top-100 prospects and another young pitcher drafted in the third round in 2023. It was the kind of deal that instantly shifts the conversation around a front office, because it says the organization is willing to trade away a frontline arm for a longer runway of talent even while the club still has a path to the postseason.
Not everyone around the game saw it that way. Harris has clearly chosen long-term value over the comfort of pressing for an immediate push, and some evaluators around baseball questioned whether that is the right call for a team still in the chase. The move leaves Detroit with more upside in the system, but it also puts a premium on whether the prospects can justify giving up one of the sport's most impactful pitchers. [Read more 🡒]
