England leads by 172 runs at Trent Bridge after Pakistan resumed on 149-7 in reply to the hosts' 354, needing 8 to ensure the English batted next.
Umar Gul was Pakistan's top scorer with a spectacular unbeaten 65, including eight fours and four sixes.
Gul took Pakistan past the follow-on target with 18 off Finn's second over, but the innings ended in the 54th over when Mohammad Asif was run out by Eoin Morgan.
James Anderson took 5-54 and Finn 3-20.
