Second Test, Faisalabad, day two (stumps)
Pakistan 462; England 113-3
Pakistan's seam bowlers reduced England to 113-3 at stumps on day two, with Marcus Trescothick out for 48, as the hosts remained in charge in Faisalabad.
Andrew Strauss and Michael Vaughan were the others to fall with England still 349 behind, but Ian Bell is 36 not out.
On a frantic day, there was a 10-minute interruption when a gas canister exploded accidentally on the boundary.
Inzamam-ul-Haq had earlier top-scored with 109 in Pakistan's 462 before being run out in controversial fashion.
Then as play ended, Shahid Afridi was seen scuffing the wicket with his boots.
England batsman Kevin Pietersen, at the crease with Bell, immediately asked Afridi what he was doing, apparently concerned about the effect his action might have on the condition of the pitch.
And the Pakistan all-rounder could yet find himself questioned by the match referee.
Up until then, and the break for the gas canister explosion, the main talking point had been the run-out of Inzamam.
The Pakistan captain was in position to top his best score against England - 148 at Lord's in 1996 - when he drove a ball back to Harmison early in the day.
The Durham paceman threw the ball back at the stumps - and Inzamam, who had not moved out of his crease, instinctively lifted his back foot as he swayed out of the line of the throw.
Umpire Darrell Hair referred the decision to the third umpire, who duly gave Inzamam out even though the rules of the game state a batsman cannot be run out when taking evasive action from a throw if he has not left his crease.
The day had begun with Pakistan 300 runs to the good and with six wickets in hand.
England had a new ball at their disposal but Afridi was in no mood to adopt a watchful approach.
Matthew Hoggard was under pressure immediately as Inzamam collected three fours from the Yorkshireman's bowling.
Afridi also took a liking to Hoggard, launching him into the stands at long-on for sixes off consecutive balls.
Pakistan's most exciting batsman had motored to 92 off 85 balls with six sixes in all before edging Hoggard to Trescothick in a floating slip position as he tried to play a deft steer to third man.
By then Afridi had completed a 145-run stand with his skipper.
Inzamam continued nonchalantly, and soon reached his 23rd Test century to share a national record with Javed Miandad.
And when he was given out, it was the tail-enders' turn to enjoy the easy batting conditions.
More wickets eventually came England's way. Harmison persuaded Naved to chop a ball onto his stumps and Ashley Giles caught Mohammad Sami off his own bowling.
Kamran Akmal hit an attractive 41 before falling immediately after lunch, caught behind off Giles.
Finally, Shoaib Akhtar, dropped by Strauss on nought, hit two sixes off Harmison before being held at long-on attempting a third in the same over.
England had the vast part of the middle session to begin their own account, but things did not go according to plan.
Strauss mistimed a pull shot which he edged into his stumps and Vaughan had reached just two when his middle stump was dislodged by a perfect inswinging yorker.
Trescothick and Bell were doing a fine job of hauling England back into the match - and were not put off their stride by the gas cylinder incident.
However, shortly before stumps, Trescothick edged a drive off Sami which wicket-keeper Akmal gratefully pouched.
