NL teams would have first crack at Murphy. Based on NL contenders and their need, I would assume Arizona would have the biggest need for help at 2B. If it was indeed the Cubs who put a claim on him, then that would be a weird fit. It would mean the Cubs are serious about moving Russell out of the starting line up and putting Baez at SS. But they could have done that without putting a claim on Murphy, seeing as they have Happ, Zobrist and La Stella who could all play 2B.
If it is the Cubs who put the claim in, and if they indeed get Murphy, this would be one of the weirdest transactions in a while. Not because Murphy is not a perfectly useful player but because of fit. I'd take him on the Cubs, but with rumors of Darvish being done in 2018 (and may be in MLB because they are rumors that Darvish is contemplating retiring from MLB and moving back to Japan), you would think SP would be a priority.
