THe only issue I have with Adam Walker is that the Twins never gave him a chance, all the while giving ABs to guys OFs like Shane Robinson, Logan Schafer, Darin Mastroianni, Jordan Schafer, and Sam Fuld. Walker showed a lot of strikeouts in the minors, but then he had consecutive seasons of 27, 25, 31, and 27 home runs. If you combine the total minor league careers of all 5 of those guys you get 148 over a total 48 minor league seasons, just 24 more than Walker did in 5 seasons.
I get it, there were a lot of questions about Walker and his ability to play at the MLB level, but then with those other five there were a lot fo answers that they absolutely could not. So, why not give the guy 100 plate appearances at the major league level to see if he could show enough power and OBP to compensate for the strike outs. I agree that he almost certainly would fail, with only a 10% chance of being a 700+ OPS hitter at best, but then they never even tried.
If I were a draftable player I would hate to be drafted by the Twins. They are going to start you in the lowest levels of the minors (ask yourself why Elizabethton wins their leagues regular season/title so often) and then slowly move you up the ladder even if you perform really well. They brought in, and continue to bring in, cast offs from other teams that they advance before you and who suck in their time with the Twins. Of the 5 OFs that I mentioned above, only Fuld had an OPS with the Twins above .700, .732 in 2014 vs. his career of .632. Jordan Schafer, .640 (career .615), Mastroianni .573 (career .551), Robinson .621 (career .592), Logan Schafer .660 (careeer .611). I would have rather watched Adam Brett Walker have a partial season with the Twins with a .600 OPS and a few launched homers than those stiffs.
But that is not the Twins Way.
