London: Glenn McGrath claimed his 500th Test wicket and added four more to haul Australia out of trouble on the opening day of the first Ashes Test against England. His opposite number, Steve Harmison, earlier grabbed five wickets as England's bowlers ripped through the Australian batting lineup, dismissing the tourists for just 190 before tea. But McGrath hit back with 5-21 from 13 overs as England finished the day on 92-7 in reply. Test debutant Kevin Pietersen helped rally England from 21-5 by sharing a 58-run partnership with Geraint Jones, who was out for 30, caught by wicketkeeper Adam Gilchrist off the bowling of Brett Lee. Ashley Giles was the last man out, hit wicket off Lee's bowling. Pietersen was not out 28. Harmison's 5-43 from 11.2 overs included 4-7 in just 14 balls as England began its attempt to end Australia's 16-year hold on the trophy. Andrew Flintoff and Simon Jones claimed two wickets each, while Matthew Hoggard took one. Harmison wrapped up the innings with the dismissal of tail-ender Jason Gillespie for his sixth five-wicket haul in 31 Tests.
