The story of a 19-year-old Mickey Mantle hitting a baseball somewhere between 550-660 feet

We've seen some incredible rookies impress over the last few years. From Cody Bellinger to Kris Bryant to Mike "The Fish God" Trout:

But 66 years ago today, a 19-year-old Mickey Mantle may have topped them all during a Spring Training game against USC. The Yankees rookie, who was auditioning for the chance to take over the center-field job from an aging Joe DiMaggio, went 4-for-5 with a single, triple, two home runs and seven RBIs. And his second homer, from the left side of the plate, went, um, very, very far.
Many witnesses say it carried over the college stadium's right-center-field fence (344 feet) and into a huddle on the adjoining football field. Future pro football player and sportscaster Frank Gifford was a Trojans tailback at the time and admitted that "no one had ever done that before."
In 1985, after hearing about the blast during a radio interview with former Yankees farmhand Woodie Held, a group of researchers set out to measure the blast themselves. They enlisted the help of the USC coach who saw the homer from the dugout that day and Trojan outfielder Tom Riach -- who remembered climbing eight feet up the wall to watch it sail across the football field. They then sat down with a photograph of the field from 1951 and mapped out the general area where it landed. The group determined it was in a ridiculous 654-660 feet range.
As for The Mick, he made the Yanks and went on to hit 536 homers (some just as far) during an 18-year Hall of Fame career. When asked about his games at USC, he was reported as saying:
"I really got a hold of a couple. Man, that was fun."
