If he doesn't slow down I can see them sending McGonigle to Toledo the last couple of weeks of the seaso to get his feet wet and be ready to start next season there, and if he starts the season at AAA and keeps it up, he'll see Detroit in '26. Based on the handling of Jobe I don't see the Tigers as being reluctant to see a guy make it quickly - IF he is performing at a high enough level. But that is still a big if.
And of course, in '26 if Gleyber is gone and Keith starts playing 3rd regularly there would be nice spot at 2B for someone to fill.
