The winner has yet to claim their prize, but has 182 days to do so, according to the lottery news release.
The winner must come in person to the Maryland Lottery's Claims Center at 1800 Washington Blvd. in Baltimore.
Saturday's Powerball drawing is worth an estimated $70 million with a $41 million cash option.
