Baker and Roberts start for BluesCarl Baker returns to the Pompey team against Yeovil this afternoon.
The midfielder has recovered from a hamstring problem and replaces Jamal Lowe in the starting 11.
That is one of two changes from the side that won at Hartlepool last week.
Gary Roberts replaces the injured Noel Hunt, with Kal Naismith moving to a striking position.
