Miguel Sano obliterated a ball into outer space on Wednesday -- crushing the piece of cowhide nearly 500 feet -- and afterward, he dedicated the moon shot to a fan he had drilled in the head earlier in the night.
The story is pretty heartwarming ... before the Twins' game against the Red Sox at Fenway Park -- Sano felt awful after he hit a batting practice homer that cracked a young fan in the head.
As Sano crossed home plate, he pointed to the fan ... and then gave the kid his jersey after the game as well!
"[The kid] told me to, 'Hit a homer for me and give me your jersey,'" Sano said. "And I said, 'Hey, I'm going to do it and I'm going to try to hit a longer one here and I'm going to give you the jersey.'"
