Pic of the Week

Ronald Acuna Jr. hits his first major league home run.

The Atlanta Braves called up the consensus top prospect in the minors last week. Ronald Acuna Jr. won't turn 21 until December, and the Braves have the two youngest players in the majors in their lineup (the other being second baseman Ozzie Albies).

Age matters. As Jay Jaffe explains in this Fangraphs piece, ANY playing time in the majors at 20 --Acuna's age, and Albies's age last year -- signals a rare talent. Acuna, simply by reaching the majors this year, has at least a 5 percent chance of reaching the Hall of Fame. Ditto Albies.

Their career arcs will be interesting to follow.
