Ronald Acuna Jr. is reaching rarefied air as a 20-year-old.
The Atlanta Braves moved Acuna to the top spot and he's been on a tear since, culminated by leading off both games of a Monday doubleheader with a home run.
That's 10 home runs since the All-Star break for the rookie, and now he's the:
• Fourth player to ever hit a leadoff home run in both games of a doubleheader. Brady Henderson was the last (1999).
• Youngest player to homer in four straight games, eclipsing a feat of 20-year-old Miguel Cabrera with the Florida Marlins.
