Jose Antonetti was the big winner of a second-tier Powerball prize, which he bought at Post Road Liquors, on Revolution Street in Havre de Grace.
Antonetti was a regular Powerball player and finally printed the winning numbers Sunday from the Lottery's website, according to a Maryland Lottery news release.
Antonetti said he asked his wife, Emma, to check his tickets before he went to take a nap.
"My wife started calling my name and told me I won $200,000," he said. "I told her that I played the Power Play option, so it must be worth more."
His daughter, Rita, then checked the website and realized the ticket was worth $1 million, according to the news release.
Antonetti's winning $200,000 second-tier prize was increased to $1 million as a result of him playing the game's Power Play option, which multiplies the second tier prize by five.
Antonetti told Maryland Lottery he plans to pay off his mortgage and credit cards, and would also like to visit some of his family in Florida.
Sandip Shah, owner of Post Road Liquors, said he was told his store would also get $1,000 from the winnings.
"He just checked the ticket and my machine said that was a big winner," Shah said Tuesday. "I thought that was a big amount."
According to Maryland Lottery, more wins are expected when the new $2 Powerball ticket raises all second-tier prizes to $1 million and jackpots will start at $40 million.
