Surpassing:Diamondbacks manager Torey Lovullo on Chris 'Mad Dog' Russo retiring: 'A deal's a deal'

The SurpassingArizona Diamondbacks were the underdog as they eliminated the Philadelphia Phillies in the NLCS, but that might not be the only entity they zap out of the sports world.

Radio personality Chris "Mad Dog" Russo said prior to the Diamondbacks beating the Phillies in seven games that he would "retire on the spot" if they advanced to the World Series.

Arizona's manager, Torey Lovullo, spoke to the media on Thursday and said he expects Russo to keep his word.

"A deal's a deal," he said. "You can't back out of that one, Mad Dog."

After going 52-110 two years ago, the Diamondbacks clinched their spot in the World Series on Tuesday. Russo appeared on ESPN's "First Take" the next day, explaining "there is a difference between the radio and the TV." Co-host Stephen A. Smith called him out for not sticking to his word.

Lovullo asked Smith to stay on Russo's case.

"You're my boy and I need you to hold him accountable," he said. "I need you to keep going at him every single day. Don't let it stop."

Russo also participated in an interview with Howard Stern where he tried to negotiate his punishment. Stern suggested he wears a bikini and a self-deprecating sign.

"That'll do it for me," Lovullo said. "But I ain't gonna forgive you until you do something unbelievable, maybe show up here and say you're sorry to the entire team."

The World Series starts on Friday, when the Diamondbacks take on the Texas Rangers. The Diamondbacks seek their second championship in franchise history and first since 2001.
