The day after the Red Sox paid tribute to the victims, survivors and heroes of the Boston Marathon bombing and manhunt, attention yesterday shifted toward lending a helping hand in the aftermath. Outfielder Jonny Gomes did his part, playing with a custom-made bat engraved with the names of the four victims and “Boston Strong,” and the team announced that it, along with Major League Baseball, the players’ association and members of the Red Sox community would make a $646,500 donation to the One Boston Fund. Gomes had four bats shipped overnight by the Victus bat company, and used two of them, one in each of his first two at-bats in Game 1 yesterday. He will eventually auction them all off. “Just trying to get the word out there, just do what I can,” Gomes said. “I’ll have the whole team sign them and then I’ll auction them off and hopefully raise some funds for where it’s needed.” The motivation was not hard to find. “I think everyone is up to something, individually or as a team, to help the community out,” he said. “It’s definitely not about me by any means, it’s just about who’s on the bat, about the cause that it’s going to help out.” The Red Sox donated $100,000, MLB donated $500,000, the club’s Foundation donated $46,500, the latter amount coming from donations made this weekend by fans. Baseball will continue to seek One Fund donations from fans via national telecasts, and the Red Sox and MLB will donate 100 percent of proceeds from “B Strong” baseball caps.
