Australian Fast bowler Mitchell Starc says pace partner Josh Hazlewood's unerring line and length will allow his fellow bowlers to let rip at England's batsmen in the Ashes Test series. Starc and Hazlewood form a potent new-ball attack for Australia in the series, which gets underway in Brisbane on November 23.

Backing them up is another New South Wales tearaway, Pat Cummins, who has been singled out by Australian leg-spin great Shane Warne as the Ashes destroyer with his searing pace. Hazlewood will be fresh and rested for the series, having played just one Sheffield Shield game since coming back from a side strain injury.

Test spearhead Starc may have captured two hat-tricks for NSW in a recent Shield win over Western Australia, but he claims Hazlewood will prove to be Australia's spark. Starc said Hazlewood's nagging line and length would tie up one end and allow him and Cummins to attack from the other.

"He's a bloody genius with line and length, it allows Pat and I to be aggressive and that's how I bowl," Starc told reporters in Brisbane on Monday. Starc, Cummins, Hazlewood and fourth paceman Jackson Bird are training together this week in Brisbane instead of playing Shield games for their state sides. Mitchell Starc has taken 17 wickets at 12.70 in this season's Sheffield Shield, but said he had yet to reach peak form ahead of the first Test.
