Manny went to pick it up barehanded to throw it in. He missed the pickup and batted it backward. He had to tell Crisp the ball was coming his way. Crisp missed both cut-off men.
It should not be scored a HR. Manny should get an error for missing the pickup, and Crisp should get an error for missing the cutoff man. I don't fault Mannny all that much on the play. He was there backing up the play. Crisp was nowhere near the ball off the fence and then he f***ed up the throw.
