Don't know if anybody has suggested this. We have Getz, who can field but not hit; Avilés, who can hit and field competently, but not exceptionally; and Betemit, who can hit but not field. When we have a flyball pitcher in, or when the other team has a lot of left-handed batters, we use the more offensive-less defensive infield, Betemit at 3rd and Avilés at 2nd. When we have a groundball pitcher in, or when the other team has a lot of right-handed batters, we use the more defensive-minded infield of Avilés at 3rd and Getz at 2nd, with Betemit possibly at DH.
