World number four Agnieszka Radwanska beat French seventh seed Marion Bartoli 6-4, 6-2 on Thursday to reach the women’s final of the Miami hardcourt tennis tournament. Poland’s Radwanska, who shrugged off a power outage that halted the match for more than 30 minutes to wrap up the victory, will face world number two Maria Sharapova in the championship match on Saturday. Radwanska ended an impressive run by Bartoli, who had handed world number one Victoria Azarenka her first defeat of 2012 in the quarter-finals.
