I agree that I'd want Andujar to get a chance. But Nunez is essentially the same player as Andujar (in terms of strengths/weaknesses), a pure hitting infielder with questionable fielding skills. I don't think you can have both of those guys on the 25 man roster. I doubt Toe is going anywhere, and Torres is almost certainly gonna start the season in AAA. So that leaves Toe, Wade, Andujar, and whoever else the Yankees add to field 2 starting spots and one utility role on the 25 man roster. If the Yankees sign Nunez then I think Andujar gets left off of the 25.. but if they sign a glove-first infielder, I think Andujar gets a spot and Wade is sent to AAA.
This is all just speculation though, for all we know Cash will swing a trade for Machado this week and make us all look like fools.
