England in command at Headingley
Pakistan were bowled out for 174 before Jennings and Cook put on 53.
England moved on to 53 for one as they made a sound start to their first innings after bowling out Pakistan for 174 in the second Test.
The recalled Keaton Jennings reached 29 in the hazy evening sunshine at Headingley before edging Faheem Ashraf to wicketkeeper Sarfraz Ahmed, bringing out captain Joe Root to join England’s record run-scorer Alastair Cook who was unbeaten on 23.
Stuart Broad, James Anderson and Chris Woakes had earlier taken three wickets apiece to put the hosts in a strong position to salvage a draw from the series, although Shadab Khan’s dogged half-century gave the tourists hope.
England, beaten by nine wickets at Lord’s last week, began the match with four maiden overs – the first time they had done so in a Test since playing Australia at The Oval in 1993 – after losing the toss.
Broad dismissed Imam-ul-Haq for a duck and fellow opener Azhar Ali for two inside the opening 10 overs, before Woakes snuffed out a promising partnership by bowling Haris Sohail (28) and Asad Shafiq (27) to leave the tourists 68 for four at lunch.
The hosts strengthened their grip on the clash after the restart, with Anderson removing Pakistan captain Sarfraz and Ashraf lbw to take his tally to 537 Test wickets, while Broad claimed his third victim of the day in between by removing debutant Usman Salahuddin.
After Mohammad Amir was caught by wicketkeeper Johnny Bairstow off Anderson, a ninth-wicket partnership between Khan and Hasan Ali boosted Pakistan’s modest score.
Ali was caught and bowled for 24 for by Woakes, while Khan made a defiant 56 before a wild slog to deep midwicket was caught by Jennings to give Sam Curran a debut wicket.
