THREE RIVERS, Mich. — 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 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.
