ZEPHYRHILLS, Fla. - Some lucky person walked into a Publix supermarket in suburban Florida over the past few days and bought a ticket now worth an estimated $590.5 million - the highest Powerball jackpot in history.

On Sunday, he loaded groceries into his car after shopping at the Publix.

"This would be the sixth Florida Powerball winner and right now, it's the sole winner of the largest ever Powerball jackpot," Florida Lottery executive Cindy O'Connell told The Associated Press.

SAN ANTONIO - Tony Parker had 20 points and nine assists, Kawhi Leonard scored 18 points and the San Antonio Spurs struck first in the Western Conference finals by beating the Memphis Grizzlies 105-83 on Sunday.

The Spurs avoided a repeat of their Game 1 loss from when the teams met two years ago in the first round.

The Grizzlies went on to knock San Antonio out of the playoffs as the top seed that time.
