For the third time in four months, a winning Powerball ticket was bought in Western Pennsylvania -- this time in Marshall, state lottery officials said Thursday.

The ticket for Wednesday's $18.7 million drawing was sold at the Sunoco A-Plus convenience store on Route 19.

The winner -- who has not come forward yet -- matched all five white balls, 11-19-25-38-50, and the Powerball, 35. The lucky buyer can opt for the full annuity value or take a lump sum payment of $10.16 million, less 25 percent for federal taxes, lottery officials said.

"It's important to remember we are the (most populous) state that plays Powerball," lottery spokeswoman Stephanie Weyant said. "So we should have more winners."

Other Western Pennsylvanians also won fortunes recently.

On Jan. 22, PNC Financial Services Group employees Karen Rodgers, Kathleen Fitzgerald and Janet Bigler, all of the Pittsburgh area, won a jackpot that resulted in a lump-sum payment of $14.7 million. They bought their ticket at Nielsen's, a newsstand inside 2 PNC Plaza, Downtown.

On Dec. 8, Florence Ayers, 69, of Jackson, her son, James Ayers, 41, of Mars and her daughter, Sharon Kreindel, 48, of Beachwood, Ohio, won the drawing that gave them a lump-sum payment of about $70 million, after federal taxes.

Scott and Marian Calligan, of Cranberry, ended up with $53.7 million in cash, after taxes, when they won the July 9, 2003, Powerball drawing. They split a jackpot with a Missouri couple. The winning ticket was bought at a 7-Eleven store in Cranberry.

Sunoco employees would not talk about the ticket yesterday. They said they only heard rumors that it was sold there. The store owner will collect $100,000 for selling the ticket.

Customers pumping gas and buying snacks were largely unaware that a winning ticket was sold there.

"There seems to be a lot of winners around here," said Rick Drossman, 47, of Cranberry. "I didn't play. I usually wait until the jackpot hits triple digits."
