The Tigers have kept Yilber Díaz in the organization, but his path back to the big leagues just got a lot narrower.
Detroit outrighted the right-hander to Triple-A Toledo, according to the MLB.com transaction tracker, after designating him for assignment on Monday when the club trimmed its offseason roster to 40. It’s the first time Díaz has cleared waivers in his career, and he’ll stay with the Tigers for now.
Díaz landed in Detroit on a waiver claim from Arizona in late June and spent most of the rest of the season in Toledo on optional assignment. He did get a few short looks with the major league club, but the results were rough: four appearances, four runs allowed, and 5 1/3 innings total. Over parts of three big league seasons, he has logged 37 1/3 innings with a 6.27 ERA, along with a 15.5% strikeout rate and an 11.9% walk percentage.
The righty had once been seen as one of the more promising starting arms in a thin Arizona system, thanks to a power repertoire. But his lack of a usable changeup and shaky command made it tough for him to hold down a rotation job, and the Diamondbacks shifted him to the bullpen in 2025.
Even there, the same issue has followed him. Díaz put up strong strikeout numbers in the minors, but he still hasn’t found enough strike-zone consistency to stick in the majors, even as a reliever. In Triple-A this season, he threw 54 innings with a 3.50 ERA, a 28% strikeout rate and a 15% walk percentage.
Díaz has exhausted his minor league option years, which means Detroit won’t have the same flexibility to shuttle him between Toledo and the majors moving forward. He should receive a non-roster invite to Spring Training.

Tigers May Have A Surprise Pitching Find Worth Watching Closely
The Tigers have spent plenty of time this season sorting through pitching depth, and Win Scott has quietly become one of the more interesting names in that mix. The left-hander, acquired from the Atlantic League's High Point Rockers, has moved through the system quickly thanks to strong showings at multiple levels, giving Detroit a developmental arm worth tracking as the organization looks for more homegrown options.
Scott's work in the Arizona Fall League has not matched the cleaner results he posted earlier, but the broader profile still stands out because of the strikeouts and command he has shown along the way. If he keeps trending in the right direction, the next steps could include more time at Double-A and Triple-A before the Tigers have to decide how close he really is to helping at the major league level.

Tigers Have A Late-Round Bat Fans Should Start Watching
Beau Ankeney spent the 2026 season making the kind of noise that can turn a late-round pick into a name worth tracking. The Tigers 14th-round selection from the 2025 draft showed real pop and enough athleticism to stand out, and after moving up to High-A he kept producing in a way that suggested there may be more here than the usual college-senior first baseman profile.
Ankeney is older than plenty of the players around him, and the swing-and-miss is still part of the package, so this is hardly a finished product. Even so, he has already shown he can do damage against different pitch types and hold his own with the bat in a tougher setting, which is enough to make him one of those deeper-system hitters Detroit fans will want to keep an eye on as the next step comes into focus.

Tigers Suddenly Have A Bullpen Question They Can't Ignore
The Tigers made a notable bullpen move on Nov. 2 when they reinstated Will Vest to their 40-man roster, a sign that they are already mapping out relief depth for the seasons ahead. Vests path back is a long one after elbow and hip surgeries in 2026, and Detroit plans to bring him along gradually once he is ready, but his return still matters because the club is trying to stabilize a late-inning group that could look different before long.
At the same time, Detroits decision to decline Kenley Jansens club option sent him into free agency, opening a question the Tigers cant really sidestep. Emilio Pagan is another name in the mix after declining his player option with the Reds, giving the front office another possible veteran arm to consider as it sorts through a bullpen that needs answers, not just possibilities.
