I am not an overall baseball fan though I follow the Red Sox pretty closely. I just don't follow any other team. I was watching a youtube ESPN 30 for 30 called 4 nights in October about the Red Sox's comeback from the Yankees after a 3-0 defecit in 2004. What interested me is watching in games one and 2 where slow Kevin Millar got on base and a pinch runner named David Roberts came in. The question is: is why do pinch runners or even base runners still wear their helmets while on base?f you need to run you think the hat might make you a little faster. Pitchers don't wear helmets and they get hit all the time by line drives. Maybe a silly question but weird.
