Rookie superstar Jackson Chourio is historically cementing his first MLB season. The Milwaukee Brewers outfielder smacked an opposite-field, two-run blast in the eighth inning en route to a 3-0 win against the San Francisco Giants Thursday night. The homer made the 20-year and 185-day-old phenom the youngest player in MLB history to collect a 20/20 season. Chourio and Mike Trout are the only players to reach the plateau in their age-20 campaigns.
