Early Life and Background
McKenzie Matthew Moniak was born on May 13, 1998, in Carlsbad, California, a coastal city in San Diego County known for producing talented athletes.

Moniak committed to attend the University of California, Los Angeles, where he planned to play college baseball for the UCLA Bruins.
