Early life Malachi Moore was born on June 14, 1990, in Compton, California. He grew up with his mother, grandparents, and older brother in a small house in East Compton. His parents separated when he was young; his mother worked for Los Angeles County, and his father was frequently on the road as a truck driver.

Moore attended Manuel Dominguez High School, where he played baseball and football. In 2006, when he was 15, his 19 year old brother was killed in a drive-by shooting. MLB’s Compton Youth Academy opened that year, and Moore spent most of his free time participating in programming and working at the academy. In his words: He was at second base, with Mike Muchlinski at first, Marvin Hudson at third, and Brian Knight at home plate. Moore worked 156 MLB games before being hired as a full time umpire in 2023, and assumed uniform number 44 in honor of his mentor Danley, who wore it before retiring after the 2021 season. His first postseason assignment was the 2024 American League Wild Card Series between the Kansas City Royals and the Baltimore Orioles.

Personal life Moore lives in Phoenix, Arizona, with his wife and two sons. He met his wife while attending college.

He runs an annual umpiring camp at the Compton Youth Academy and is active with UMPS CARE.
