Entering his third big league season, Stanton is drifting more toward his birth name. Already, some teammates are calling him Giancarlo (pronounced JEE'-ahn-cahr-loh), and on Wednesday night he changed his Twitter handle to @Giancarlo27_.
His full name is Giancarlo Cruz-Michael Stanton. But he's been called Michael since childhood.
"It was just easier," he told The Associated Press. "If you can't pronounce that, then there's something wrong with you."
The name plate above his locker at Roger Dean Stadium reads Giancarlo Stanton, which also is the name on his bats. But even last year, Giancarlo Stanton was above his locker.
Baseball fans will hear plenty of Giancarlo references, because he's asked that be used when he's announced.
So get used to, "Now batting, Giancarlo Stanton."
Still, that doesn't mean the 22-year-old is moving entirely away from being called Mike.
"I respond to many names," Stanton said. "It's all good."
