Nolan Jones went to Tito and said he wants to try first base. At Columbus they were working with Benson at first base (before he was promoted) and now Arias.
I guess nobody is all that impressed by Owen Miller.
The search for a corner outfielder who can also play first base from time to time when Naylor could use a day off or a DH day continues. First it was Jake Bauer. Then Josh Naylor, who was playing right field when he had his injury. Now that Naylor is no longer an outfielder they're looking at Benson and Jones as possibilities.
Another option is a middle infielder who can also play first. Yu Chang didn't work out and neither is Miller, so far. Looks like Arias is the next one up.
A right-handed bat would be ideal for that role, IMO, so they can rest Naylor against certain lefties. So I think Arias might have the edge over Jones and Benson. It also might be easier for an infielder to play first base than an outfielder with limited experience playing ground balls.
