Jason Heyward started his Major League Baseball journey on Opening Day in 2010 with a home run on his first swing—at the age of 20.

He went on to have one of the better rookie years in recent memory, including ending up with the fourth highest on-base percentage (.393) in the National League.

Freddie Freeman’s journey will really begin (he was called up last September) this year, as he will be the team’s first baseman barring a catastrophe in spring training. He ripped up AAA last year and will look to continue his dominance with his best friend for the next 15 years in Atlanta.

The two were best friends, having been drafted in the same year for the Braves, and rose through the minors together until Heyward broke through last year. Being best friends won’t bring up any Barry Bonds-Jeff Kent moments up between the two.

These two both have great potential to do big things at the plate and on the field, while both being great people as well.

Here are 10 reasons while the two 21-year-olds will form the best duo in all of baseball going forward.
