This is a surprisingly light price for the 27 year old Cole, who was the first overall pick in the 2011 draft. Cole is two years away from free agency and is considered to have top of the rotation stuff, although the results haven't always been there. His 2017 season was mildly disappointing, as he essentially put up 203 league average innings.
Feliz is a 24 year old righthander with really good stuff and really significant command issues. He's got a career 5.13 ERA in the majors working out of the bullpen, but who knows, maybe the Pirates think pitching coach a Ray Searage, who has a solid track record with reclamation projects, can do something with him.
Musgrove, 25, has split time between the bullpen and the rotation for the Astros over the past season and a half, putting up a 0.7 bWAR in roughly 170 innings.
Moran, 25, spent last season in Fresno with an OPS a little over 900. He's had brief stints in the majors, and the big question with Moran is whether he has the power to be a productive corner guy.
Martin, 22, is a left fielder who spent last year in high-A and AA and was left unprotected in the Rule 5 draft last month.
