Well, as someone who's followed Alex Jackson a bit, the Mariners were probably looking to get what they could for him, since he's been a bit of a bust. He was rated I believe one of the top hitters coming out of the 2014 draft, but hasn't lived up to expectations. That said, he's only 20 and played in Hi-A Ball last year. His 2015 season was abysmal, but 2016 was a bit better, but the K rate is very troubling. If, and that's a big if, he puts it all together, he could be a star. That's looking like a long shot though at this point.
What do Whalen and Povse project to turn into?
