Narrowing the hole to just 1 corner of the zone is pretty huge, since it should if nothing else make it easier to layoff those pitches and wait for the pitcher to miss for a ball or end up coming down or in farther. Just as importantly in my book is showing that he can make the adjustments and is likely then to keep adapting throughout his prime years. I think he'd look really good as a primary RF now if we brought up Lara.
On the health front he is now 2 PAs shy of his career high.
Miz days look like a good time to play him at 3rd. Looking at the Spray chart I counted 9 ground balls total in the 3rd base area (I had to guess from the chart about where the line between 3rd and SS ends up). Just looking at OBP difference between Vaughn and Hamilton. If you assume just 3 Plate appearances per start while Miz is in. Hamilton gets on base 13 times compared to 18 for Vaughn. So yes it looks like the offense/defense trade off there makes sense.
Worth mentioning that the league minimum is up to 780,000 now. So my quick math indicates even a waiver wire pickup saves the Brewers almost 450K. He is owed about 2.3 million for the rest of the year.

Based on this year's data Joey's bat will play better at 3B, yes SS have outhit 3B league wide. Catcher is the only worse batting position, compared to 3B
You could probably even do a top 30, but only vote on 25 as you would almost certainly get enough differences in the 20-25 range to have 30 different players or more earning votes.
If the swap is really Pratt for Rengifo, the floor on that improvement for the team is around 1 WAR. Which isn't tremendous but is about as good as most deadline deals that work out ever are anyway. And that's conservatively putting Pratt on the low end for a debut (again every SS for the Brewers has hit better in their debut by WRC than Rengifo was doing this year.) Right now that 1 Win would put up to the number 2 seed so definitely valuable to be able to set-up our rotation and skip the wild card round in my book. And importantly I have yet to see anyone propose an actual likely to be dealt viable needle mover between either 3rd base or SS. I would love to see Lara in CF and think between the offense and the defense it could definitely be a big improvement for the team.
I also think it's a relatively low pressure situation for his debut. Not just midweek against an AL team, but overall a lot of the reason for the focus on the left side of the infield was because we already had those obvious alternatives to call-up. Now we have done that and Hamilton has already shown he can provide OK production at 3rd. Keep the batting average up over the Mendoza line and take some walks and we'll spend most of our time waiting for Miz's next start and worrying about his innings at the same time now.
I think Pratt underperforming whatever combination of Rengifo and Ortiz he does offensively is relatively unlikely. Solid strikezone control and good bat to ball skills make that hard to do. As you say there's a good chance it's a lateral move for this season, but one with a reasonable chance of there still being more upside. I think he's done enough as well that you can look at it as him getting that rookie season out of the way and boosting his chances for more development at the plate next year too. Keeping Ortiz around as the utility guy for defense and some platoon protection for Hamilton works fairly well since he's hit better than Rengifo and has the way better glove.
Had other obligations this afternoon, so get home log into Brewers see not only did we win but Harrison absolutely remembered how to pitch after suffering through Las Vegas and Pratt is getting promoted. One heck of a weekend series
Baseball Reference indicates that ties Miz for the 6th highest Game Score on record

No pitch counts available for the Ryan games but no chance those were under 100 pitches. Spahn maybe the only one on that list who could have been as efficient
For comparison in terms of dominant games here is the box score for the Kerry Wood game.

Are the later year buyouts guaranteed? Specifically if the Brewers declined the 33 option would they still have to pay them? It doesn't have a huge impact on the value of the deal. The 'front loading' I would think is part of the appeal for sure. Yes he had a good signing bonus, but he is going to have millions more in the bank then he would have if he waited for Arbitration and then the big FA deal. Looking at the breakdown and its almost certainly more raw income until at least 2031 this way.
