Glover posted a final round of three over to emerge victorious at Bethpage
Lucas Glover said he hoped he would not "downgrade" the US Open title after his unlikely victory elevated him alongside the sport's most illustrious stars.
"I dreamed about it as a kid and pulled it off," said Glover, who came into the tournament ranked 71st in the world.
"It's an honour to be on the trophy with names such as Jack Nicklaus, Arnold Palmer and Tiger Woods. I hope I don't downgrade it or anything."
Glover fought off a late charge from Phil Mickelson to win his first major.
A cool birdie at the 16th - his only hole below par in a three-over final round of 73 - enabled him to shake off the world number two, who was being roared on by the vociferous galleries at Bethpage before having to settle for his fifth runner-up spot at the US Open.
And Glover said he had been expecting a final-round charge from Mickelson and world number one Woods, who eventually finished tied for sixth, four shots back.
"We were waiting on it," he said.
"You knew Tiger and Phil were going to make a move, and they did. And Ricky [Barnes] and I started coming back. That probably motivated them more.
"But I was watching them. You have to. I just like to know where I sit and what I need to do."
The result was the 29-year-old's second tournament win in eight years as a professional, his only other victory coming in the Funai Classic at the end of the PGA Tour season in 2005.
