The Boston Red Sox, Major League Baseball, the Players' Association and fans have made a $646,500 contribution to The One Fund Boston.

The One Fund Boston is the nonprofit organization set up to help those affected by Monday's Marathon bombings.

The donations include $100,000 by the Red Sox, $500,000 from MLB and the MLBPA and $46,500 from the Red Sox Foundation, a result of contributions made by fans at Fenway Park.

"Baseball has become an integral part of the Patriots Day celebrations here in Boston," Red Sox principal owner John Henry said.

"When the game ends, many of the more than 37,000 fans walk from Fenway Park to the finish line to cheer the marathon runners on Boylston Street. This tragedy directly affected many of our most ardent fans. We continue to send our sympathies to all who have felt the impact of these terribly sad events."
