I could see Baltimore as a team that the Brewers match up with for trades. Others have mentioned this previously in other threads, so this isn't a fully original thought. The Orioles should be competitive next season but certainly could use a #1/#2 starting pitcher. Bautista's injury means they could also use a closer. Corbin Burnes and Devin Williams would both be potential trade targets for Baltimore. Such a combination deal should bring high return back for the Brewers.
Baltimore has a lot of near-MLB-ready infield talent in their upper minors. They already brought up Gunnar Henderson, Jordan Westburg, and Joey Ortiz to the majors. They probably have room for one more of their prospect infielders (e.g. Coby Mayo, Jackson Holliday). But it seems like they have a similar problem as the Brewers: more IF prospects than spots in the lineup, like Milwaukee has more OF prospects than spots in the lineup.
So Baltimore seems to be a good matchup. Target Mayo as the cornerstone of a trade deal to become the longterm 3B in Milwaukee. Scanning Baltimore's Top 30 prospects, you could look to pick up several others. I'd look to include both Samuel Basallo (C) and Connor Norby (2B), both in their Top 10. Target a pitching prospect for the last player return (Chayce McDermott?) or look for two A/A+ players (high ceiling/mid-to-low floor).
I'm sure others may have better ideas, but Baltimore seems like one of those "it just makes sense" type of trade targets.
