Levan Mchedlidze scored twice as Empoli pulled away from the drop zone with a 2-0 home win over Cagliari.The Georgian striker had both of his goals laid on by Guido Marilungo, who picked out Mchedlidze in the Sardinians' box in the eighth minute before finding his team-mate again 18 minutes from time.Empoli dominated from start to finish and Marilungo could have got on the scoresheet had he directed a right-footed shot on target just after the half-hour mark.Cagliari had a late opportunity to halve the deficit but substitute Joao Pedro saw his penalty saved by Lukasz Skorupski.
