LONDON (AFP) Stuart Broad starred with both bat and ball as England pressed for victory in the fourth and final Test against Pakistan at Lords here on Saturday. Broads sparkling 169, his maiden first-class century, helped England to a first innings total of 446, with his stand of 332 with Jonathan Trott, who made a painstaking 184, a new Test world record for the eighth wicket. And Broad, primarily a fast-medium bowler, then struck twice - including dismissing star batsman Mohammad Yousuf for nought - as Pakistan slumped to 10 for three. Pakistan, 2-1 down in the series, were 46 for three at tea on the third day a deficit of 400 runs with Broad having taken two wickets for 10 runs in six overs. Broad continued a memorable match when he had Yasir Hameed caught at second slip by Graeme Swann off a rising delivery. And nine for one became nine for two when left-handed opener Imran Farhat drove flat-footedly at James Anderson and was caught behind by wicketkeeper Matt Prior. Yousuf had been a thorn in Englands side during his return to Test cricket at The Oval where Pakistan won by four wickets last week. But he was out fourth ball on Saturday when 24-year-old Nottinghamshire seamer Broad produced a superb full late outswinger that clipped the off-bail. Off-spinner Swann troubled Salman Butt by turning the ball sharply away from the left-hander but the Pakistan captain survived to be 26 not out at tea. Azhar Ali was unbeaten on 10. Earlier, Trott almost became the first player to score two Test double hundreds at Lords, following his 226 against Bangladesh in May. But his stay of more than nine hours, featuring 19 boundaries, came to an end when, chasing a wide delivery from left-arm quick Wahab Riaz, he edged a and was caught behind. Trotts methodical approach was just what England needed after the rest of the top-order were undone by superb swing bowling on Friday, with only his fellow South Africa born batsman Kevin Pietersen giving his wicket away. Trotts partnership of 332 with Broad surpassed the previous eighth-wicket Test-best of 313 shared by Wasim Akram (257 not out) and Saqlain Mushtaq (79) for Pakistan against Zimbabwe at Sheikhupura in 1996/97. Teenage left-arm quick Mohammad Aamer, wicketless on Saturday, took six for 84 with the 18-year-old, who dismissed Pietersen, Paul Collingwood, Eoin Morgan and Swann for ducks, becoming the youngest bowler to 50 Test wickets. England resumed Saturday on 346 for seven with Trott 149 not out and Broad unbeaten on 125. They had come together at 102 for seven after England had been 39 for four and 46 for five earlier in the innings. Trotts legside single off Aamer, to the first ball he faced Saturday, saw him to 150. Broad, on a day where blue skies above Lords made conditions ideal for batting, followed him to the landmark with a superb cover-driven boundary off Mohammad Asif, having then faced 273 balls with a six and 14 fours. Broad, dropped on 121 on Friday, produced an array of stylish shots that bore comparison with crickets great left-handed batsmen, let alone his father Chris, the former England opener whose six Test hundreds were all made abroad. But his magnificent six-and-a-half hour innings ended when he missed a sweep against off-spinner Saeed Ajmal and was given out lbw on referral. Broad was just shy of the world record score by a Test No 9 of 173 made by New Zealands Ian Smith against India in Auckland in 1990. SCOREBOARD ENGLAND, first innings (overnight: 346-7): A.
