I think the Baines shout for automatic selection is nostalgia now.
We have three on an equal footing for that position atm: Baines, Oviedo and Galloway. Baines is about the worst defender of the three. For that reason (given our self imploding tendency at the back) I'd have him down the pecking order.
I think he's underrated defensively. A fair point though Oviedo is very solid defensively. I don't see it yet with Galloway but alternatively I really like Garbutt so swings and roundabouts.
One of the things I like about Martinez (it's not in vogue to praise him) is he knows how to utilise a squad. There is none of this "if you're not in my first team you are not needed" stuff that you got with say a Moyes or a Rodgers. I think Martinez will value his experience in and around the dressing room. I also think he will rotate him more and keep him fresh as well as using Baines more innovatively in different positions. I wouldn't be surprised to see him deployed in midfield wide or centrally going forward.
I heard people saying we made a mistake not keeping Cahill in a squad role. I am inclined to agree now. The same goes for Baines. England internationals needs to be utilised, even if they can't play every game.
As for Oviedo he is a very good back up. He is also a very adept squad man, can fill in at right back and across the midfield and I have never really seen him let us down. I hope he can have an injury free run and can get a new contract.
My own guy feeling is Garbutt may fill the role as a specialist but I have no issues with Oviedo when playing direct wingers as he is very adept at that.
