From 194 for three at tea, England lost six wickets for 26 runs to be 221 for nine when bad light forced an early close on the third day.That left England, looking for a 3-0 lead in this four-match series, just 146 runs ahead with one second innings wicket standing.
Off-spinner Ajmal, who bowled 30 overs unchanged, had four wickets for 71 runs and left-arm quick Aamer four for 51.
Stuart Broad was six not out and Steven Finn nought not out.Earlier, opener Alastair Cook ended a poor run of scores with an innings of 110 but that was all but eclipsed by England’s final session slump.
Ajmal started the collapse with a clever piece of bowling.From around the wicket, he beat Kevin Pietersen’s defensive push forward with a fine off-break. Five balls later, 194 for four became 195 for five. Jonathan Trott played a supporting role during a third-wicket stand of 116 with Cook.
Having taken three-and-a-half hours to make 36, Trott played a rare attacking shot and was caught in the gully by Azhar Ali off Aamer.
