Unofficially, Catherine Pugh remained in the lead after provisional and absentee ballots were counted in Baltimore.
While the results still need to be certified, unofficial numbers were available Friday.
Those numbers show former mayor Sheila Dixon gaining 139 votes since election night bringing her total to 45,219. Pugh received a total of 48,665 votes.
The numbers won't be certified until Monday. After that, Dixon's campaign has three days to ask for a recount.
