England's push for a historic series victory against Pakistan was blunted by an excellent partnership between Imam-ul-Haq and Saud Shakeel, before Jack Leach made a crucial late breakthrough to leave the hosts needing 157 runs to win and England needing six wickets.
Having resumed as firm favourites with a lead of 281 on day three, England ultimately set Pakistan a target of 355 to win, one that would be their second-highest successful chase if they were to pull it off. It took Brook just 20 minutes to score his second England century, reaching three figures off 137 balls with an emphatic pull for four.
However, after Pakistan broke the 101-run partnership between Brook and Ben Stokes when the England skipper holed out for 41, the hosts quickly ran through the lower order. Pakistan took the final five England wickets for just 19 runs, giving them a chance of chasing the target and levelling the series.
