Chicago Cubs top rookie prospect Pete Crow-Armstrong hit is first major league hit and 2-run homerun. Derek Mitchell the person who caught the ball asked to exchange the HR ball for game used bat. After the exchange Derek discovered some discrepancy between the bat he received and the HR from videos on social media. Cubs team official asked Crow-Armstrong about the exchange and Crow-Armstrong said he didn't hear the fan asking specifically for bat used for his first MLB hit.

Was there some miscommunication with this exchange or did Crow-Armstrong pull a fast one?
