If those are the prices, then give me Bryce Miller. The difference between him and Gilbert isn't worth PCA & Brown, imo. Miller throws a full tick slower, but he's a year younger, has two extra years of control and has otherwise similar FIP metrics. The other concern is the fly ball rate, but Gilbert's not exactly a ground ball machine, either.
I think I'd rather just pay Yamamoto, but I can understand preferring to go in this direction for established MLB performance + salary difference. For me, that preference may just come down to whether or not Stroman opts in or not.
