Lottery officials say the winning ticket to a $310.5 million Powerball jackpot was sold in southwestern Michigan.
Michigan Lottery spokesman Jeff Holyfield says the winning ticket in Wednesday night's drawing was sold at a gas station in Three Rivers. He says the winner hasn't come forward yet.
The winning numbers were 21, 39, 40, 55, 59 and the Powerball was 17.
The Michigan lottery says Wednesday's jackpot is the second-largest this year.
In February, players in North Carolina, Puerto Rico and Texas split a $564.1 million prize.
