• Pakistan 154-1 at tea
• Aslam 69 not out, Azhar 72 not out
• Anderson removes Hafeez for nought

Anderson induced a rash stroke from Azhar shortly after lunch but Joe Root spilled a difficult catch at second slip and England's frustration mounted.

Azhar drove Steven Finn off the back-foot for three to bring up his 21st test half century and Aslam, 20, swept spinner Moeen Ali for four to reach his maiden test fifty in his third match.

The four-match series is level at 1-1.
