Alastair Cook has scored his second successive century to help put England in a promising position at the end of the second day of the second Test against Australia.
The batsman finished the day on 136 not out with fellow hitter Kevin Pietersen on 85 not out.
That saw England finishing on 317 for two in Adelaide and leaves them 72 runs ahead.
Cook scored 17 boundaries in his 246-ball stay at the crease while Pietersen cracked 13 fours as he moved within sight of his first century for 21 months.
England did not made the best of starts - Strauss chose to leave the third delivery of the day, only to see it clip the top of his off bail. He was gone for just a single.
However Jonathan Trott put in a better display and he and Cook spent most of the first two sessions continuing their torment of Australian bowlers.
Trott eventually went shortly before tea - bowled and caught for 78.
England continued to bat well and will hope to do so long into day three.
With a new ball just three overs old the home side need to capitalise with early wickets, especially that of Cook who has now batted for over 1,000 minutes since his last dismissal.
