I get it and probably agree that Quinn is the better player between the two. The L/R platoon would have given Haseley more playing time so I imagine they are just trying to get Haseley 2 starts a week and Quinn is the de facto starter. I am fine with that and keeping Haseley as injury and late inning defense.
I just kind of wish that some of the ABs that have been going to other players like Walker and Gosselin could have been used to get Haseley in the lineup a little more often. There is more there than he has showed thus far. Also, I don't know if you have watched Cutch on defense, but his arm seems limited. The range is there but his throws just are not.
