Colby Bishop’s double helped a below-par Portsmouth beat Shrewsbury 3-1 to move another step closer to promotion.

Table-topping Pompey started with two centre forwards and the early pressure paid dividends when they took the lead on three minutes.

Conor Shaughnessy crossed from the left and Shrews skipper Chey Dunkley could only put the ball into his own net.

Pompey were in total control but their lethargic and scrappy play produced little.

Shrewsbury took advantage and equalised on 29 minutes. A break on the left saw the ball reach an unmarked Jordan Shipley in the box and he easily beat home goalkeeper Will Norris.

Conceding seemed to wake Pompey up and they regained the lead three minutes before half time from the penalty spot.

Clever play by Kusini Yengi resulted in him being brought down and top scorer Bishop converted.

Shrewsbury played the second half with more purpose but Pompey finished the job off with 14 minutes remaining when Bishop slammed home from 10 yards.

Victory left Pompey nine clear of third-placed Bolton with four games remaining.
