ATLANTA (AP) — An ironworker and his wife presented the winning ticket for a $275 million Mega Millions jackpot on Monday and said they'll use part of the windfall to replace their trailer home with a new house in coastal Georgia.

Robert Harris said he picked the winning numbers from Friday's multistate drawing — 7, 12, 13, 19 and 22, plus the Mega Ball number 10 — by using his grandchildren's birthdays.

"It's awesome," Harris, 47, told a room full of reporters after receiving the ceremonial big check from lottery officials. "We have been very blessed."

The jackpot is the single largest in the history of the 15-year-old Georgia Lottery and the third largest in Mega Millions history, lottery officials said.
