  We present preliminary study of parton distribution inside the pion using
mixed action approach with HYP smeared valence clover quarks on HISQ sea within
the framework of Large Momentum Effective Theory. We use 2+1 flavor $48^3
\times 64$ HISQ lattices with lattices spacing of a=0.06 fm and valence quark
masses corresponding to pion mass of 300 MeV.
