The Arizona Diamondbacks entered the playoffs as the lowest seed in the National League.

On their way to the World Series, they have been fueled by their doubters.

"If you're in any sort of competitive field and somebody tells you [that] you can't do something or they think somebody can do it better than you, I think that's kind of the main reason probably why you're where you are today," Zac Gallen said.

"I don't think it was necessarily that people thought we couldn't do it, it was just that no one expected us to be here."

Torey Lovullo is in a friendly war of words with ESPN "First Take" and MLB Network "High Heat" personality Chris "Mad Dog" Russo, who said on his radio show that he'd "retire on the spot" if the Diamondbacks won Games 6 and 7 of the NLCS in Philadelphia.

"A deal's a deal," Lovullo said. "You can't back out of that one, 'Mad Dog.' You've got to do something. ... .I ain't going to forgive you until you do something unbelievable, maybe show up here and say you're sorry to the entire team. That's all I want to say about that."
