Face value - I really like this trade. I have been wanting the Twins to go after Gray for years, and now we've got him for affordable rates at $10M and $12M for 2022 and 2023. I like adding him rather than going after guys like Pineda and Cueto.
Losing Petty hurts, but he's years away from relevance and the odds of him panning out aren't all that high. Even better, moving just one prospect for Gray presents a considerable risk for Cincinnati, so say if Petty's career gets sidetracked by injuries (see Span for Meyer trade), the trade is complete loss for the Reds.
More moves like this, please! We have a considerable glut of pitching prospects, but if the aim is to win now, let's make more trades like this one.
