Head coach Rex Gonzalez grew up in Tampa, Florida surrounded by baseball from an early age. His father, "Red," founded the Bay West Umpires Association, making Rex no stranger to the baseball fields. He graduated from Thomas Jefferson High School in 1989, and played college baseball at Faulkner State, followed by a transfer to the University of South Alabama (1993-1994). His first stop in professional baseball was with the Mobile Bay Sharks in the Texas-Louisiana League (1994-1995). Rex then went to the Western Baseball League and played for the Grays Harbor Gulls in Washington (1995-1997). His last stop was in California with the Salinas Peppers (WBL). After his playing career, Rex moved into coaching, first with Grays Harbor Gulls as the Hitting and 3B coach, and then moved to Nevada to coach the Reno Black Jacks. In 2000, Rex was the Manager for the Feather River Mudcats in Marysville, CA. In 2010, Rex founded AZ T-Rex Baseball Club. His nephew, Jacob, named the organization, which is a point of pride for Rex. Aside from pitcher, Rex has played every infield and outfield position during his professional playing career.
Being bilingual and of Cuban descent, Rex works closely with the Arizona Diamondbacks to make charitable trips to border towns in Mexico to donate baseball equipment and direct educational baseball camps for the local youth.
