Rovers are 11-4 to claim all three points in Saturday’s Sky Bet League One clash at Portsmouth.
Rovers are unbeaten in their past five clashes with Pompey, winning their past three.
That was a run kicked off with a memorable 2-1 win the last time the two sides met at Fratton Park, with John Marquis and Andy Williams on target for visitors.
Marquis is 2-1 with EFL sponsors Sky Bet to repeat that feat and get on the scoresheet, building on his strike against Bristol Rovers last weekend.
Portsmouth are 11-10 to come out on top, while a draw is priced at 11-5.
