Australia have their eyes set on regaining the top Test ranking as they take on West Indies in the second Test which starts in Melbourne tomorrow. Steve Smith’s men are currently ranked third, behind South Africa and India. A win against the Caribbean side will see the Aussies seal the three-match series and also hand them crucial ranking points. Their prospects have been boosted by the return of fit-again top-order batsman Usman Khawaja. Shaun Marsh has been dropped to make way for Khawaja.
