"I think we're going to have a pretty good turnout," Tampa Bay manager Joe Maddon said.
The growing list contains the names of Brandon Gomes, Cesar Ramos, Sam Fuld, Wade Davis, Elliot Johnson, Alex Cobb, Matt Joyce and James Shields, to name a few. Coaches Dave Martinez and Tom Foley have also signed up.
Maddon hatched the idea for the fundraiser to raise awareness and money for pediatric cancer.
Those interested in contributing to the fundraiser can text the word "cut" to 50555 to make a $10 donation. Or you can visit http://www.pcfcutforacure.org.
When asked whom he most looked forward to seeing without hair, Maddon noted: "Me."
"Otherwise, [we have] young good-looking guys on the team, [getting their hair buzzed] doesn't matter," Maddon said. "It's like Demi Moore in 'G.I. Jane.' If you're good looking, you're good looking. For those of us who are not, we have something to be concerned with."
