So Romero is at 110 innings so far. His cap before getting shut down completely is probably, what, 150 innings? It sure would be nice if 20-30 of the remaining innings were in Minnesota.
I'm not sure what the front office is going to do, but if he stays at 5 innings a start through the end of the month, would add about 25 innings to his total. Would potentially make sense to call him up in September, give him 2 inning outings every 3 days or so, give him a taste. Never let him come in the middle of an inning.
I would very much hesitate to call him up for starts in the bigs, but a limited bullpen role when the rosters are expanded could be a good way for him to wind him down this year and break him into the bigs. You could then start him at AAA next year, build up the pitch counts and innings, give him a taste of success, and he could be ready by mid-May as a rotation replacement with the potential to make it through the season.
It's not popular, but I would keep Gonsalves down through the end of the Chattanooga season. He'll need some more innings, so could call him up after that for some end of the year starts in the bigs, or perhaps send him to Arizona. Would put him in good position to start next year at AAA and be ready as a rotation replacement relatively quickly next year.
Finally starting to build some meaningful minor league depth.
