Colby Bishop scored twice as Sky Bet League One leaders Portsmouth moved closer to promotion to the Championship with a stylish 3-1 victory at Wycombe.

Pompey are now 11 points clear of third-placed Bolton after extending their unbeaten run to 13 games and need three more victories to seal a return to the second tier after 12 years away.

Portsmouth led after just three minutes when Bishop’s shot from Abu Kamara’s cut-back took a big deflection off Ryan Tafazolli and looped beyond Wycombe goalkeeper Franco Ravizzoli.

Wycombe were quick to respond and drew level in the seventh minute when Richard Kone laid the ball into the path of Matt Butcher, who fired past Will Norris.

But Pompey were back in front after 28 minutes as Bishop steered another low ball across by the lively Kamara first-time into the bottom corner.

The result was effectively in the bag for the visitors midway through the second half when Kamara’s chipped cross fell for Christian Saydee and, although Ravizzoli got gloves to his effort, he could not keep it out.
