(CBS) Former MLB pitcher Mark Mulder, who graduated from Thornwood High School in South Holland, took to Twitter on Wednesday morning to accuse Jackie Robinson West of having cheated for years.

On Wednesday morning, Little League International announced it had stripped the national title from Jackie Robinson West that it won last summer because the team drew players from outside its boundaries.

It’s impossible to know how much, if any, truth there is to Mulder’s accusations. When asked on the Spiegel and Mannelly Show on Wednesday morning if this trouble traces back before 2014, Evergreen Park Little League vice president Chris Janes — who was the whistle-blower in prompting the investigation — said he’d heard rumors in years past but that it’s wrong to spread rumors without evidence.

Janes has been a volunteer Little League coach in the suburbs for about a decade.

“There’s been rumors of innuendo circulating around for that organization for years,” Janes said. “But that’s all it’s been. There’s been no proof that I’m aware of that they’ve been cheating. All I have firsthand knowledge of is this year.

“It would be unfair to make an unfounded allegation. If all you’ve got is rumors, you should keep that to yourself. But when there’s those things and you did a little bit deeper and you find driver’s registration, voter’s registration associated with zip codes well outside their boundaries, now I have reason and fact-based reason to bring it forward.”
