We have to consider the nature of recovery from labral tears/surgery to address pathologies. The thing Ashby does have going for him, if you look into the literature, is he didn't tear his rotator cuff. Is it a glowing quality? No. Labral recoveries are anything but certain. As literature has advanced, it would appear a return to form happens in 60-80% of the players who experienc such issues - with 20% or so never playing again.
However, If you watch his recent outings, as I have, it's pretty clear he currently is working through restricted movement in his throwing shoulder and, well, this is to be completely expected given what he has endured this past year plus. By my eyes, he is working through things in a step-by-step manner - ie, he isn't opening up and why would he after a labrum surgery? That would likely lead to catastrophic effects. Just watch the two clips below - above from a 12 K outing versus the Cubs before the shoulder injury and below from yesterday's outing. It is quite clear to my eyes he is essentially getting mound work and likely working on a few things related to stacking. He isn't remotely close to a full opening of his release plane and his patented full body follow through. He's upright. And, honestly, almost casual. Like he's relearning how he pitches - step-by-step.
I personally think this is going to take at least two years to return to real semblance of his former self. But, that's just me, perhaps. I hope they take it really slow. It's impractical to expect him to contribute in 2023 to anything other than his recovery process.
