COLUMBIA, Mo.  Only something so heavy could lighten their burden. Three men gripped a 150-pound headstone around the edges, lugged it 40 feet across the grass and lowered it into the dirt.

“Got it?” the anesthesiologist asked, tilting the slab in gently.

“Yeah. Yeah, over here,” the insurance man said.

They rose from their knees, brushed off their hands and stood back from the grave.

“Big Bill Gatewood,” the historian said with a sigh.

For almost 50 years, William M. Gatewood lay in obscurity in an unmarked grave here at Memorial Park Cemetery. But that ended Tuesday, when three baseball fans continued their quest to locate every former Negro leagues player without a headstone and do their share to right the wrong.
