To be fair, Rosario hasn't hit 32 HR or driven in 100+ runs on a regular basis either -- 2019 was the only time he reached either, in a season of record-breaking HR totals all over. Although he would be on pace to do so again in 2020 but with a long way to go. His overall wRC+ from 2019-2020 is only 102, barely above the cumulative MLB LF performance during that time (~99). He has ranked top 10 in outfield assists 3 times in his 6 seasons, although again I'm not sure how to consider that relative to his overall performance. He's definitely not without value, but he definitely seems to be in the zone where you'd look for top prospects to either exceed his performance or at least equal it, overall, at a cheaper salary (thereby allowing the team to spend those resources elsewhere). Sure, as a rookie, that might be a fair median projection. Although HR and RBI are going to be playing-time (and batting-order) dependent. But the nice thing about rookies is that you don't have to promote them, or you can demote them, if they're not playing well. And if the Twins have 4 quality prospects they could try in this spot, they can probably get at least 1 out of the 4 to perform better than that median projection. You might lose a regular season win or two in Rosario's spot, but with the money you save, you may be able to make that up elsewhere on your roster. And of course, for a well-built and deep team like the Twins, regular season wins may not be quite as valuable anymore as postseason wins (especially if expanded playoffs are here to stay). Is Rosario an impact player in a short series?
