Get the nothing manacles bro ! <| sep |> A simple once over of this trade makes me like it for both sides . The Mariners get the biggest potential impact player for the next season or two in Segura which is the Mariners window for winning . And they also get two pieces that can help them now and potentially in the future . The Diamondbacks get the best value piece in terms of performance versus length of contract in Walker who also has potential to be the best player who switched teams in the long and short run . Plus they get a SS who can fill in for them in the meantime whose baseline isn ' t entirely known just yet . I ' d call it a winwin in the here and now . Long term I think the M ' s will regret parting ways with Walker , unless they have their eyes on trading for an SP who ' s better than any of the current FA market SP ' s .
