A winning Fantasy 5 ticket purchased in Encinitas is worth $543,579, the game's largest jackpot in about six months, state lottery officials announced Monday.
The ticket for Sunday's drawing matched the winning numbers 19, 23, 32, 35 and 36.
The lottery said someone bought the ticket at a Vons grocery store at 453 Santa Fe Drive.
The winner, who has not stepped forward, has 180 days to claim the prize.
Lottery officials say the daily Fantasy 5, in which a player chooses five numbers out of a field of 39, has some of the best odds of any of their games.
