Australia cricket coach Mickey Arthur has watered down suggestions by captain Michael Clarke that the side might take a four-pronged pace attack into the second Test against India, saying he was “loath” to go into any Test without a spinner. Arthur said Saturday that Australia's pace attack, led by Peter Siddle, James Pattinson and Ben Hilfenhaus, has the potential to be the world's best and he's happy with his top six batsmen after the home side's 122-run win in the first Test at the Melbourne Cricket Ground. Clarke suggested the recalled Ryan Harris could make it four pace bowlers in the starting 11 for the test starting Tuesday at the Sydney Cricket Ground, but Arthur said “the SCG has normally got a history of favoring spin down the line.” Arthur, however, said the fast bowlers have the potential to be the best pace attack in the world. Arthur said Siddle and BenHilfenhaus along with Pattinson were impressive in the emphatic in the Melbourne Test. Fellow paceman Ryan Harris, named to the squad for upcoming the Sydney match, combined with those left out of the 12-man group — Patrick Cummins, Shane Watson and Mitchell Starc — meant there was room for depth.
