Where they don't really report or scout, he was about to be added to the Yankees short season team, he just got added to the Aqua Sox roster for the Mariners.
I think the problem with Encarnacion is that teams don't highly value high slugging hitters that are limited to 1B/DH, Carlos Santana was a salary dump, EE was a salary dump, Domingo Santana was acquired for a 4th outfielder, Vogelbach was acquired for a bullpen long man, Ryon Healy cost a middle reliever to acquire, Nelson Cruz had to wait till February to get a contract with a 2nd year option.
I look at the Segura trade as primarily returning JP Crawford (who through his first 80 PA is already outhitting Segura). The other half of that trade resulted in shipping out James Pazos (who spontaneously combusted and was last seen getting roasted in Albuquerque) and Juan Nicasio (much reviled by Mariners fans, and now pitching as a 4+ ERA middle reliever) for essentially 20 homers, and 2 young pitching prospects. So essentially;
Plus (but not Plus Plus) Offense SS expected to be a 2B by '20 + 7th Inning Reliever + Junk Reliever =
Young SS ~= to Old SS + 2 B Prospects (Campbell, Then) + 3 x $14 mil/season to throw at SP in the offseason.
It's not necessarily a heist...unless one of those prospects turns into something.
