PHOENIX -- Playing in only his 400th Major League game on Monday, Giancarlo Stanton hit his 99th and 100th career homers, lifting the 23-year-old into some rare air.
Stanton joined Bob Horner and Eddie Mathews as the only players in MLB history to make their big league debuts before their 21st birthdays and then hit at least 100 homers in their first 400 games. Age distinction aside, the outfielder became the ninth player and the first in franchise history to accomplish the feat. Ryan Howard and Ryan Braun are the only other active players to have done it.
"It's remarkably how quickly he's done it," Marlins manager Mike Redmond said. "We all played with Mark McGwire, Sammy Sosa, Barry Bonds, but I don't think I've ever seen someone hit a ball harder than he does. He truly crushes the ball, it's pretty amazing. It's a big milestone for such a young guy."
Caught up in the game, Stanton didn't realize until after the Marlins recorded the final out in Monday's 3-2 win that he reached the milestone. So when Redmond handed him the game ball, it caught him off guard at first.
"That was really cool," Stanton said. "I knew I needed seven to start the season, but I lost track."
