went to a ballgame the other night, got there a little early while the Texas Rangers were taking BP, and most of the Rangers' pitchers (other than that night's starter) were standing in the outfield shagging flies that were hit fairly close to them. this happens before every game for every team in the majors. what else are they gonna be doing during that time?
That's fine, but it's not common knowledge about how far Rivera took it. He once made three over the fence steals in a session. His routine was not the norm.
