And I cannot even count the amount of times Ive seen the hitters lean over the plate to get a hit-by-pitch, and they are rewarded a base.
Saw one the other day where the batter swung through the plate, the replay showed the ball tipping back off the bat, and the girl jumped up and down and told the blue it hit her on the finger and he gave her the base!
Either way, it's a dead ball strike if the batter swung the bat.
