One of the most random statistics in baseball, a sport filled with them, is that Bryce Harper has yet to face a pitcher young than him in the Major Leagues.

Harper, 22, made his debut nearly three years ago on April 28, 2012 and has 1,497 plate appearances under his belt. He has faced approximately 375 different pitchers in his Major League career, none of them born after he was on Oct. 26, 1992.

This will inevitably come to an end, but when?

I took a look at the Washington Nationals' schedule to determine what opportunities Harper has to face a younger pitcher.

Archie Bradley of Arizona Diamondbacks caught my eye. The Nationals will travel to face the Diamondbacks at Chase Field in mid-May. Bradley, however, was born two months and six days before Harper in 1992. Bradley will make his Major League debut on Saturday against the Los Angeles Dodgers.

The first legitimate threat to Harper will come June 1-3 when Washington hosts the Toronto Blue Jays for a three-game series. Toronto has famously gone with a young pitching staff early this season, giving them a few chances to become a Jeopardy question a few years from now.

Aaron Sanchez, 22, is more than three months older than Harper, but John Gibbons has used a pair of relievers through the season's first three games that are just 20 -- Miguel Castro and Roberto Osuna.

Castro and Osuna are both right-handers, so it's tough to determine which is more likely to take the mound during that Washington series. Gibbons has already shown a willingness to shake up his bullpen, removing Brett Cecil from the closer's role after just two games, so June is a long way from now.

If Harper gets through the Toronto series without facing Castro or Osuna, there is one threat remaining (based on current Major League rosters). Jason Garcia, 22, was born less than a month after the Nationals outfielder and is working out of the bullpen for the Baltimore Orioles. The Nationals will travel to Baltimore right before the All-Star break from July 10-12.

From there, September callups are all that stand in Harper's way of another season of relative innocence.
