Roundtable Table Tigers For February 14: Digging into how deep the starting rotation will go
A few weeks ago, we talked about Jace Jung as a bat-first infielde r trying to solidify where he fits long term. The question wasn't whether he could hit. It was where the glove would ultimately land.

Now, with Jung taking reps at first base in camp, according to Chris McCosky of Detroit News, the Tigers may be offering a glimpse into that answer.
This isn't panic. This isn't a demotion. This is roster math.
For much of his minor-league climb, Jung has been viewed as a second baseman with offensive upside. The left-handed swing, the on-base skills, the ability to backspin the ball to the pull side, those have never been in question. What evaluators have wrestled with is defensive versatility. His actions at second have improved. His hands are playable. But if you're building a contender, "playable" isn't always enough.
Taking reps at first changes the conversation.

First base is not simply a fallback position. It's a way to keep a bat in the lineup while maximizing roster flexibility. If Jung can handle first base even at an average level, it opens up multiple alignment possibilities for manager A.J. Hinch and president of baseball operations Scott Harris.
Think about it.
The Tigers are trending toward athleticism and defensive range up the middle. If they prioritize a plus defender at second, Jung's offensive value doesn't disappear. It simply shifts. First base becomes a path to at-bats rather than a barrier.
There's also the platoon element. Jung's left-handed bat profiles well against right-handed pitching. If Detroit leans into matchup advantages, having him capable of playing first gives Hinch the ability to rotate pieces without burning the DH spot every night. That matters over 162 games.

And let's be honest about modern roster construction. The days of static defensive homes are fading. Harris has consistently emphasized flexibility and optionality. Jung taking reps at first is exactly that. It's preparation, not desperation.
From a developmental standpoint, this is smart timing. Spring is where you experiment. It's where footwork around the bag can be drilled daily. It's where infield instructors can hammer home positioning, feeds, and the nuances that separate "can stand there" from "can save outs." First base demands soft hands, anticipation, and internal clock awareness on double plays and bunts. It isn't automatic.
Offensively, nothing changes. Jung's value is still tied to his ability to control the zone and drive the baseball. If he's posting strong on-base numbers and showing gap-to-gap power with 15-20 home run potential, the position becomes secondary. The bat will carry him.
But the optics matter.

If Jung proves competent at first, it signals that Detroit views his bat as close to major-league ready, even if the defensive puzzle isn't fully solved elsewhere. You don't expand a player's defensive portfolio unless you're trying to create pathways.
Could this hint at a future where Jung becomes a hybrid corner option? Possibly. Could it simply be insurance? Also possible.
What it definitely is, though, is strategic.
The Tigers are no longer in a place where prospects are handed jobs based on draft status. They're building layers. They're building contingencies. Jung taking ground balls at first fits that blueprint.

And if you circle back to what we wrote weeks ago, about his bat needing to force the issue, this might be part of that forcing function. Hit enough, and the organization finds you a spot.
Even if that spot comes with a first baseman's mitt.
