Pompey were unable to find a way through a resolute Middlesbrough defence as their Championship clash ended in a 0-0 stalemate at Fratton Park.
Steve Cotterill’s side edged the first half of the game and twice came close to netting the opener as Hermann Hreidarsson’s header rattled back off the underside of the crossbar, while Dave Kitson saw a close-range shot blocked on the line by Rhys Williams.
But Boro looked the more threatening after the break as Pompey struggled to make Paul Smith do anything too taxing in the Boro goal.
Substitute Marvin Emnes perhaps had Boro’s best chance as he slipped through and Jamie Ashdown had to be alert to save with his legs.
But on reflection, a draw was probably about a fair result with neither side quite doing enough to claim that they deserved the win.
Cotterill may feel Pompey’s first-half display warranted a goal but Boro will argue that they deserved at least a point for their efforts.
