On Dec. 13, Fuld will partner with SLAMDiabetes to conduct the tournament. Some of the proceeds will serve as a fundraiser for Fuld's diabetes camp.
SLAMDiabetes has "held these Wiffle Ball tournaments in New England for the past couple of years," said Fuld, who has Type I diabetes. "They do a good job. They've been really successful.
"They roll out a truck with equipment and set up these replica stadiums. They have Yankee Stadium, Fenway Park, all of that. We're going to do it at [the University of South Florida in Tampa]."
Fuld said the tournament will be 12 teams, with nine players each.
"Basically, it's open to anybody," Fuld said. "We're trying to fill up roster spots. I'm recruiting other Major League guys. There should be a number of current and former Major League players. A lot of Rays and other guys that are in the area.
"It should be fun. According to the guy who runs these tournaments up in New England, they're a blast. Sort of a different way of fundraising than holding a golf tournament. I have a little uncertainty about how it will go, but I'm confident it will be fun."
Fuld finished the 2014 season with Oakland. To his credit, he has refused to let Type 1 diabetes run his life, which is one of the messages he passes on to campers every year at the diabetes sports camp he hosts.
