Overthrow

I am in a discussion with a gentleman on another web site (Quora.com) regarding a thrown ball going into dead play area.  My original trivia question to that forum was what 5 ways a player can get on base WITHOUT hitting the baseball.  He and I agreed on 4 of the 5…1) base on balls, 2) hit batter, 3) catcher’s interference, and 4) third strike past ball.  My 5th was a pinch runner.  His 5th was a pick off attempt with the thrown ball by the pitcher going into dead ball territory.  He claims the rules state that the batter is awarded first base, I contend that the batter is not.    Any input from anyone??

We’ve seen ML services time and time again. The ball is back in the pitcher’s hands after a play, but a base runner is dancing about 10 feet from a base, challenging the pitcher to try to get them out with a throw.
