The New York Yankees unveiled new signing Alex Rodriguez on Tuesday to huge interest from the world's media.
Rodriguez, regarded by many as the best player in baseball, joins the Yankees from the Texas Rangers in one of the most dramatic moves in recent history.
"Wow! What a reception," the 28-year-old told over 300 members of the media. "I'm just so overwhelmed and happy to be here.
"I still feel like someone's going to
pinch me and wake me up."
Rodriguez moves in exchange for second baseman Alfonso Soriano and another unnamed player.
Texas will pay $67m (£35.5m) of the $179m (£95m) left on the American League MVP's $252m, 10-year contract.
Yankees captain Derek Jeter was on hand to welcome Rodriguez, who insisted he was happy to move from shortstop to third base to accommodate the skipper.
He also played down reports that the pair do not get on following criticism of Jeter's captaincy in a magazine article by Rodriguez three years ago.
"Derek has four world championships and I want him to have 10," said Rodriguez. "That's what this is all about.
"We haven't been as close in the past because of the distance, but there is no rift here.
"That's behind us. It's so overblown."
Jeter added: "Everyone wants us to not get along, but that's not the case. Our relationship is fine."
