ST. PETERSBURG, Florida — The Powerball and Mega Millions jackpots keep on growing.

There was no jackpot winning ticket sold for Saturday's Powerball drawing, and its top prize is now $620 million. The next drawing is Wednesday.

Saturday's winning numbers were 16, 54, 57, 62, 69, with a powerball of 23.

Meanwhile, the Mega Millions jackpot is at $1.6 billion in the wake of Friday's drawing.

It costs $2 to play Mega Millions but the odds of winning the jackpot aren't good. The chance of matching all six numbers and taking home the grand prize is one in 302.5 million.
