Bobby Witt Jr. / Julio Rodríguez

In what has been a very exciting season thanks to the on-field accomplishments of some of Baseball's brightest young stars, a special pair made some history during Saturday's action. Kansas City Royals rookie Bobby Witt Jr. and Seattle Mariners rookie Julio Rodriguez are now only the second pair of first-year players to record 20-homer, 20-steal seasons in Major League history. Joining Ellis Burks and Devon White, who pulled off the feat in 1987, Witt Jr. and Rodriguez have excited fans with their play all year long, both competing for American League Rookie of the Year honors.
