Depends on what kind of success. I think his stuff alone, even if he remains as wild (5 BB/9) as he is now, means he'll likely stick in a MLB bullpen for the foreseeable future. But is he a dominant late-inning guy like he looked to start the season? Having watched his every MLB outing so far, I have my doubts about that. If you split the difference between the statcast xERA and FIP/xFIP he is a mid-3s ERA type guy this year. Which is good, but not elite. But I don't think it was so much about any concerns over him, just a case of needing to give up something good to get a good player in return. I think the Rays are one of the organizations least likely to overpay for "hype", but even so there would be at least some degree of "selling high" on J.P. Sometimes it doesn't click for players until relatively late, that could be the case for him, but there's also a very good chance there is not. And when someone is a relief-only prospect who spends 6+ years in the minors with good but not great numbers, that often (but not always!) tells us something. We don't know who else TB were interested in if JP was off the table, but I can certainly see why the Brewers would rather give up a bullpen piece, albeit a seemingly good one, over a higher-impact and higher-ceiling guy. I agree that this is a likely win-win type of situation. Adames has put up 6-8 WAR over ~2 full seasons worth of PAs and is 25. Richards looks like a useful, if low-ceiling, pitcher. The Brewers side of it is very likely to be good. For the Rays it's almost like playing with house money. They have 3 top 100 middle infield prospects in AAA (Franco, Walls, Brujan) and another (Edwards) a bit further away. If even one of them pans out, they are as good or better than they were with Adames, and so any return they got for Adames goes straight into the win column. So even if that ends up "only" being two controllable middle relievers, the Rays are an organization who knows how to make the most out of that. The Rays long-term strategy of always infusing talent even when it means "selling" while contending is painful at the start, but do it for 5+ years and you'll always have replacements coming through. This trade is a defensive upgrade at SS, and it also frees up Urias to be the injury replacement for Wong, to improve offense from 3B over Shaw, improve infield defense when needed (Urias at 3B, Shaw 1B) and to still probably get some starts at SS against lefties. So it upgrades multiple positions, and Richards makes up for some of the lost bullpen production. And having seen Adames over the last couple of days, I feel even more positive than I did when it happened. Like I didn't really worry about his 2021 numbers, but you never really know when you just have a stat line to base it on. Having seen him and his approach at the plate, I very much buy that he is the career 102 wRC+ guy and not the 80 of this year. Rasmussen is the real prize TB got back though. He, too, is not a sure thing by any means. Two TJS already, some command/meatball issues, it carries risk. But also tremendous upside if he stays healthy and improves command even a little. It's really easy to like the Rays and their organization. Since I got the package that lets me watch every MLB game this year, I have watched at least six of the their games, and combined with the WS last year, they are becoming my second team. I really agree with the "house money" aspect of the quoted post above. I am also excited about Adames on the Brewers. Hope both teams win the trade.
