Fans invited to watch Run to Home Base, try on David Oritz's MVP ring tomorrow

Fans are invited to Fenway Park tomorrow to watch runners cross the finish line at home plate for the 5th annual Run to Home Base, a 9k run that benefits the Red Sox Foundation and Massachusetts General Home Base Program, one of the only private sector clinics in the U.S. dedicated to helping Iraq and Afghanistan veterans and their families heal from the "invisible wounds" of war - post traumatic stress and traumatic brain injury.

Fenway Park gates will open at 6 a.m. for the run. Fans can enter through Gate C for the free event. Those attending will also have an opportunity to try on David Ortiz's actual 2013 World Series MVP ring that was presented to him for his 2013 postseason performance.

The ring will be available from 8 a.m. to noon in the Big Concourse, and from 1-5 p.m. at Gate E. The three World Series rings will also be available to try on. Fans are asked to purchase a Red Sox Foundation World Series ring raffle ticket on site to try on the rings. Raffle tickets start at $10 with five chances to win. Proceeds will benefit the Red Sox Foundation.

The foundation's World Series ring raffle gives fans a chance to win their own set of authentic, World Series rings by purchasing tickets online at and at the ballpark during games. The raffle will run until July 27 with a grand prize comprising the 2004, 2007, and 2013 World Series rings.
