Barry has a history of being generous to the Hall of Fame. Though he hasn't donated anything from home run No. 700, we have numerous artifacts already in Cooperstown from his career.
Think about trying to find anybody who caught two home run balls in the same game, and I don't think you can find anybody, ... Put it in the context of the historic game played here, and it's really amazing. Shaun's gesture is the ultimate act of selflessness.
