Agar bowls straight breaks - useful enough with the white ball, not the red
Agar should only make the side if his batting gets up to a 40 average and he becomes a batting all rounder or we want a dart spinner on a dustbowl.
so basically any match on the sub continent.
Leg spinners generally get slogged on the sub continent which is why i'd be going for Agar. I think he will do really well. He is super fit, good fielder and a good player of spin.
