They have been more impressive on the road of late, as 2-1 victories at high-flying Swansea and Norwich last week have underlines, but at Fratton Park they are strong, too, and can make Scunthorpe's long trip fruitless.
Steve Cotterill has made some terrific signings in Jamie Lawrence and Dave Kitson from Stoke, while David Nugent has recaptured the form that got him an England call-up. Since Brian Laws' departure the Iron have completely lost their way and another defeat looks likely here.
To make up the Yankee, take Nottingham Forest at 4-6 to beat Crystal Palace, in-form Barnsley at a massive 10-3 to win at Millwall with Stan James; and Sheffield Wednesday to exploit the possible fatigue of Exeter who had to go to penalties in midweek (6-4 Hills).
Banker: Portsmouth to beat Scunthorpe 4-6.
Yankee: Portsmouth to beat Scunthorpe 4-6; Nottingham Forest to beat Crystal Palace 4-6; Barnsley to beat Millwall 10-3; Sheffield Wednesday to beat Exeter 6-4
