Teenage debutant Ashton Agar fell agonisingly short of becoming the first Test match No 11 to score a century but still helped give Australia the edge in their Ashes opener against England at Trent Bridge on Thursday.

England, at tea on the second day of the first Test, were 11 for two in their second innings with Mitchell Starc on a hat-trick after removing Joe Root and Jonathan Trott with successive deliveries.

Earlier it seemed England would have a commanding first innings lead as Australia collapsed to 117 for nine in reply to the Ashes-holders' first innings 215.

But 19-year-old Agar went on to make 98 — the highest score by any Test No 11, surpassing Tino Best's 95 for the West Indies against England at Edgbaston last year.
