The Red Sox Foundation will present a worldwide raffle of World Series rings for the next nine weeks. The grand prize is a set comprising the 2004, 2007, and 2013 rings. Raffle tickets, which start at $10 for 5 chances, are available online starting today, Wednesday, April 23, at 10 a.m. at redsox.com/ringraffle. The raffle will continue until Friday, June 27, at 11 a.m.

The second place prizes is a pair of 2013 World Series rings. Third place winners will receive a single 2013 World Series ring. Each ring will be personalized with the winner's name.

"We are pleased to offer Red Sox fans the chance to have their own World Series Championship ring collection," said Red Sox Foundation Honorary Chairman Tim Wakefield. "We hope fans around the world will participate in this unique opportunity which supports the Foundation's efforts to help families throughout New England."

Raffle tickets include more incentives with larger purchases.

The ring raffle will be run by NetRaffle.org, part of the Celebrities For Charity Foundation, and Major League Baseball Advanced Media.  

Net proceeds from the raffle will help fund the award-winning programs of the Red Sox Foundation and help hundreds of charities throughout New England.

While this is the third time the Red Sox Foundation has conducted a World Series ring raffle, it is the first to be conducted nationally and worldwide. After World Series victories in 2004 and 2007, the foundation raised over $1.9 million and $1.3 million, respectively, for the raffle of the 2004 and 2007 World Series rings to individuals in Massachusetts.
