A lucky ticket sold in Rapid City matched the five white ball numbers, but not the red Powerball number, to win the game's second prize in Saturday night's drawing.

Lottery director Norm Lingle said the ticket holder should sign the back of the ticket immediately, put it in a safe place, and call the Lottery office in Rapid City, at 394-5106, or Pierre, 773-5770, tomake arrangements to validate the ticket and claim the prize.

The winner has 180 days to claim the prize.

The winning numbers for the April 11, 2009 drawing were 07, 28, 35, 46, 49, and the Powerball was 20. The Power Play prize multiplier was 4.

Two other South Dakota players have already won Powerball's $200,000 prize this year. Toni Smith of Custer won Jan. 17, and James Janisch of Eden won on Feb. 11. There were only two South Dakota second-prize winners in 2008.

The odds of winning the game's $200,000 second prize are 1:5,138,133.

Because no one correctly matched all six numbers in Saturday's drawing the jackpot will grow to an estimated $25 million for the Wednesday, April 15 drawing.

Powerball is played in 30 states, the District of Columbia and the U.S. Virgin Islands. The odds of winning the jackpot are 1:195,249,054.
