His career included a notable trade to the New York Yankees in the 1980s, a return to the Oakland Athletics in 1989, and a pivotal role in helping the A's secure the World Series title that year against the San Francisco Giants.

Henderson was a symbol of Oakland, embodying the city's spirit with his swagger and fierce competitiveness, which resonated with fans and players alike.

Veteran MLB manager Buck Showalter regarded Henderson as a one-of-a-kind player, recalling his dedication to fitness and conditioning, which set him apart from his peers.
