Pakistan’s seam attack was highlighted as a danger prior to the series and their first skirmish with the England batsmen ended in their favour.
Shaheen Afridi trapped Rory Burns (4) leg before wicket, before Abbas (2-24) did likewise to Dom Sibley (8), and then claimed the prize wicket of Ben Stokes for a duck, the ball clipping the off-stump with a subtle nip away off the pitch.
Captain Joe Root (14) was subdued and then out, edging leg-spinner Yasir Shah to wicketkeeper Mohammad Rizwan.
Pakistan resumed the second day on 2-139, but added only 48 runs in the morning session at a paltry rate of 1.85 per over, also losing key batsman Babar Azam (69), Asad Shafiq (7) and Rizwan (9).
But for the first hour after lunch, they upped the tempo considerably as Shan and Shadab Khan (45) punished England’s limp attack, adding 105 runs in little more than 25 overs for the sixth wicket.
Shan batted for 319 deliveries to anchor the innings before he was trapped leg before wicket by Stuart Broad (3-54).
Pakistan’s long tail was wrapped up with fiery fast bowler Jofra Archer (3-59) contributing to their demise.
