The Ohio Lottery said Patricia Edwards, of Troy, matched all five white balls in the Dec. 17 drawing. Had she matched the Megaball as well, the 54-year-old would have won part of the $648 million jackpot.
Lottery officials said she made her claim on Dec. 23. Her $1-million prize was one of 11 sold for the drawing, and the only one in Ohio.
Edwards bought her ticket at a Speedway in Troy, which gets a $1,000 sales bonus.
The winning numbers for the drawing were eight, 14, 17, 20 and 39, with a Mega Ball of seven.
