LONDON (AFP) - Shane Watson took five wickets in a Test innings for the first time as Australia edged ahead in their series opener with Pakistan at Lords here on Wednesday. Watsons return of five wickets for 40 runs helped Australia dismiss a largely inexperienced Pakistan side for just 148 in reply to their first innings 253. That gave Australia a lead of 105. They were 100 for four - an overall advantage of 205.
