The Hall of Famer passed away Sunday at his home in Danville, CA. A family spokesperson says Morgan had been diagnosed with polyneuropathy -- a disease that affects the nerves.

Despite only standing 5'7" tall, Morgan was a force on the field -- racking up more than 2,500 hits during his 22 seasons in the big leagues.

Morgan made his MLB debut in 1963 and played until 1984 -- playing for 5 teams during his run including the Houston Colt .45s/Astros, SF Giants, Philadelphia Phillies and Oakland Athletics.

He's most famously known for winning 2 World Series titles with the "Big Red Machine" in Cincinnati in 1975 and 1976.

On top of the world titles, Morgan had a trophy case full of personal accolades -- 2-time National League MVP, 10 All-Star appearances, 5 Gold Gloves and 1 Silver Slugger.

His #8 was retired in Cincinnati in 1987. He was inducted into the Baseball Hall of Fame in Cooperstown in 1990.

After his playing career, Morgan became a successful broadcaster -- calling MLB games for ABC Sports, NBC Sports and ESPN.

He was so popular, they used this voice in the MLB 2K video games.

Reds CEO Bob Castellini released a statement on Morgan's passing, saying, "The Reds family is heartbroken. Joe was a giant in the game an was adored by fans in this city."

"He had a lifelong loyalty and dedication to this organization that extended to our current team and front office staff."

"As a cornerstone on one of the greatest teams in baseball history, his contributions to this franchise will live forever."

The baseball world has lost several legends in recent months -- including Tom Seaver, Lou Brock, Bob Gibson, Whitey Ford.
