What happened

Alex Jackson cleared waivers and was outrighted to Triple-A St. Paul, per Steve Adams of MLB Trade Rumors, completing the third designated-for-assignment cycle of his 2026 season with the Minnesota Twins. The Triple-A season has already concluded, making the assignment largely procedural — but the procedural part matters quite a bit financially.

Per the report, Jackson is expected to accept the outright assignment rather than elect free agency. The reason is straightforward: accepting keeps him entitled to the remainder of his $1.35MM guaranteed salary for the season. Rejecting the assignment in favor of free agency would mean forfeiting whatever is left of that guarantee. He followed the same logic on both prior occasions this season, clearing waivers unclaimed and accepting outright assignments to the minors each time.

Once the regular season concludes, per MLB Trade Rumors, Jackson would be eligible to become a minor-league free agent — unless the Twins move quickly to re-add him to the 40-man roster before that window opens.

Why it matters

The roster spot Jackson vacated went to first baseman Aaron Sabato, whose promotion from Triple-A St. Paul — previously reported — was made official by the club, per Adams. The Twins' handling of Jackson over the final stretch of the season is worth a closer look, because it was, to put it charitably, unusual.

As longtime Twins writer Aaron Gleeman noted, Minnesota carried Jackson on the roster for 44 games dating back to August 1 but gave him only five plate appearances across that entire stretch. He was operating as a third catcher behind Ryan Jeffers and Victor Caratini, with a secondary role as a backup option at first base, and was described by the report as generally kept around as an insurance policy. Five plate appearances in 44 games is a usage pattern that raises an eyebrow even by the modest standards of a third-string catcher — it is less a roster spot than a very expensive seat in the dugout.

The sequence that preceded this final designation added another layer of peculiarity. Per the report, the Twins designated Jackson for assignment ten days after the trade deadline, then immediately re-selected him to the major-league roster a few days later when he passed through waivers unclaimed. That round trip — designation, waiver wire, re-selection, 44 games, five plate appearances, designation again — is the kind of roster management that defies easy summary.

The numbers

Jackson's career MLB line sits at .175/.254/.305 with a 39.6% strikeout rate across seven partial seasons and six organizations, per the report. Those are not numbers that explain a long big-league career; they are numbers that explain why a former No. 6 overall pick has spent that career in journeyman fashion, accruing nearly four years of service time without ever settling in as a regular.

The more recent sample looks considerably better on the surface. Per MLB Trade Rumors, Jackson posted a .256/.312/.444 batting line — a 112 wRC+ — across 173 plate appearances split between the Twins and Orioles over the past two seasons. That is a legitimately solid output, and it is worth acknowledging. It is also worth acknowledging, as the report does, that it has been supported by a .376 average on balls in play, a figure the report notes he is not going to sustain over a larger sample. The 35.3% strikeout rate sitting underneath that line is a more durable signal.

What has never been in question is his defense. Per the report, Jackson is a quality defender behind the plate, with particular strength in controlling the running game. In a sport that increasingly values what happens behind the dish as a measurable skill, that reputation has kept him employed through three designation cycles in a single season — which is, in its own way, a testament to something.

Where the club stands

The Twins enter the final days of the regular season at 75-84 (.472), sitting third in the AL Central, 7.5 games back in the division, and eliminated from both the division race and the Wild Card race. Their Wild Card ranking sits seventh, 6.5 games relative to the cut line. They have won their last two games.

Minnesota closes out its home schedule with a three-game series against the Texas Rangers at Target Field. Joe Ryan is the probable starter Friday, September 25. Bailey Ober is lined up for Saturday, September 26. Sunday, September 27 goes to Dean Kremer, who was traded to the Twins and has posted scoreless starts since joining the club, per earlier Posterior Wire reporting.

With the postseason no longer in the picture, the final series is less about standings movement and more about the kind of late-September evaluation that shapes roster decisions over the winter. Sabato's promotion — the move that directly displaced Jackson — fits that context. The Twins now get a look at him on a major-league roster as the season winds down.

What we don't know yet

The most consequential open question, per the report, is what happens once the regular season ends. Jackson would be eligible for minor-league free agency at that point unless the Twins act to protect him by restoring him to the 40-man roster. Whether Minnesota has any interest in doing so — given the three designation cycles in a single season and five plate appearances across 44 roster days — is not addressed in the report.

It is also worth noting that the report frames Jackson's acceptance of the outright assignment as something he "will surely" do, given the salary mechanics, but that remains an expectation rather than a decision he has publicly stated. He has made the same choice twice before this season, which makes the expectation a reasonable one.

What to watch

The minor-league free agency window is the next meaningful moment in this story. If Jackson is not returned to the Twins' 40-man roster before it opens, he would be free to sign with any organization — and given his defensive reputation, it would be surprising if there were no interest. Whether that interest comes with a 40-man spot attached, or another minor-league arrangement with a spring-training invitation, is the question that will define what the next chapter of a genuinely unusual career looks like.

For the Twins, the more forward-looking question is what Sabato's September showing produces. The Jackson era in Minnesota — three designation cycles, one re-selection, 44 games, five plate appearances, $1.35MM — is, for all practical purposes, over. The insurance policy has expired.
