Wow. This is a pretty huge deal for this early in the year:
#Dbacks acquire C Wellington Castillo, RHP Dominic Leone, INF Jack Reinheimer & OF Gabby Guerrero from Mariners for Mark Trumbo & Vidal Nuño
— Arizona Diamondbacks (@Dbacks) June 3, 2015
So the Diamondbacks did want Welington Castillo all along. They just didn’t want him from the Cubs.
In all seriousness, having lost Tuffy Gosewich for the year, the Diamondbacks were in the market for a catcher even more than they were before, and Castillo could be a guy for them for the next few years.
The return here for Mark Trumbo appears mostly to be about the prospects, each of whom look to be fairly decent gets for the Diamondbacks.
In other words, this looks like a pretty clear “sell” trade for the Diamondbacks, who were not expected to compete this year. Then again, they do have Yasmany Tomas to slide into the now vacant outfield spot, so maybe they won’t take much of a hit overall just yet. That’s fairly significant, given that a couple of the Cubs’ primary Wild Card opponents (the Giants and Padres) play out west.
The deal is also significant because it has the potential to kick off trade season much earlier than in years past (the Cubs and A’s mostly set things off last year a full month later in the season). You don’t know how these kinds of deals impact other talks around the league, and it’s possible that this winds up shaking a few other things loose. You also don’t know whether any of the other AL West teams will now feel a little more urgency.
