A native of Rochester, New York, Van Wieren had been calling games for the Triple-A Tidewater Tides when the Braves hired him before the 1976 season to join a new three-man broadcast team with Caray and Ernie Johnson.
The trio would soon become known to baseball fans around the nation thanks to Turner, the team's brash owner, who began beaming games via satellite on a once-obscure Atlanta television station. While the team didn't have much success through the 1970s and '80s, Johnson, Caray and Van Wieren were the faces and voices of the game in areas that didn't have their own local broadcasts.
With his thick glasses and thinning hair, Van Wieren didn't fit the classic television mold. But his smooth voice and ability to come up with obscure statistics in the pre-Internet era paired especially well with Caray, who was known for his biting sarcasm and irreverent retorts. They were inducted into the Braves Hall of Fame in 2004, joining their good friend Johnson. He died in 2011.
Chipper Jones, who spent nearly two decades as the Braves third baseman, became a fan of the team while growing up in Florida, largely because of Van Wieren and those TBS broadcasts.
"Grew up watchin him every night," said Jones, who retired after the 2012 season. "We will miss you buddy!"
Dale Murphy, who starred for the Braves during the height of the team's popularity on the SuperStation, tweeted that Van Wieren was a "true professional, great friend and pillar of the Braves family."
Van Wieren's talents went beyond baseball. He also called NBA games on TBS and TNT, in addition to stints with the NBA's Atlanta Hawks, NHL's Atlanta Flames and Big Ten Conference football.
In 2010, he released a memoir of his long career, "Of Mikes and Men: A Lifetime of Braves Baseball."
Van Wieren was initially diagnosed with lymphoma in early 2010. He was treated for the disease, but it returned before the year was out.
"This is certainly not what I planned to do when I retired," he told MLB.com at that time.
Van Wieren is survived by his wife of 50 years, Elaine, sons Jon and Steve, a daughter-in-law and three granddaughters.
A private funeral will be held.
