Diamondbacks pitcher Zack Greinke hasn't said anything about Colorado reliever Pat Neshek's autograph claims.

But Arizona Diamondback fans have come to his defense, flooding social media after the Rockies pitcher called out Greinke on Tuesday for refusing to sign some baseball cards for him.

Neshek called Greinke a "turd" and "ahole" for reneging on what he said was a promise to sign some baseball cards for his son.
