DES MOINES, Iowa (AP) — The Powerball jackpot will grow to an estimated $730 million after there were no winners Saturday for the lottery's top prize.

The results come as there was also no winner of the Mega Millions jackpot on Friday.

That top prize is now estimated at $850 million. It's been nearly two years since a lottery jackpot has grown so large. The Powerball's $730 million top prizes would be the fifth-largest ever if a lottery player strikes big in Wednesday's drawing.

The Mega Millions' $850 million jackpot would be the third-largest ever for the drawing on Tuesday.
