$500 million.

That number is so hard to wrap your brain around, but it's a number a lot of professional baseball players may soon start seeing on their contracts.

One player who could be the first to see that amount within the next year is Nationals right fielder Bryce Harper.

Harper will become a free agent in 2018 and people are already projecting his market value at close to $500 million, if not more.

Miami Marlins right fielder Giancarlo Stanton signed a contract back in 2014 for 13 years, $325 million, holding the league record.

For Fancy Stats writer Neil Greenberg, $500 million is a bargain for someone of Harper's caliber.

"Harper is every bit as good [as Stanton] but he's also young," Greenberg told the Sports Junkies Friday.

"I mean, we don't see a player that's as good as Harper, that's as young a Harper, hit the market almost ever I want to say. You look at how many years of his prime he has left and then even if you start to give him just the typical aging curb off of that prime, he's probably worth close to 570 million dollars starting from 2019 and going forward ten years. And that includes also the price of free agency going up and other factors."

Harper, who is only 25 years-old, brings more to a team than just talent. He's one of the most recognizable figures in baseball, bringing tremendous marketing opportunities to an organization. Greenberg dove deeper into how that will increase his market value.
