• NLCS Game 4: Today at 8 p.m. ET/ 7 CT on FS1
"I really appreciate the compliment, we all do," Maddon said. "The seed of doubt is one of the most significant tools you can incorporate against your opposition, but full disclosure, we're not doing it."
Zobrist also thought the accusations were laughable and responded on Twitter: "This is hilarious ... umm ... no I was not stealing signs. Glad you think my baseball IQ is that high."
Maddon isn't even comfortable with the concept.
"What you have to be aware of is, if you're going to relay [a sign], the guy at second base has to be 100 percent certain, or you could get somebody hurt at the plate," Maddon said. "You have to have a guy who has been around a bit and has done it before successfully at different levels. I wish we were good at it."
• Maddon was still smiling on Tuesday about Aroldis Chapman's invitation to join some of the Latin American players in the back of the plane on the charter flight to Los Angeles on Sunday night.
"It was a 20-minute giggle fest," Maddon said. "We talked and laughed and saluted each other. Everybody's in good shape, let's go. It was a real happy moment."
One message that Maddon made sure the relievers received going into the postseason was that they had to be ready at any time. He's tested that with Chapman by bringing him in with runners on base in both the Division Series and the NLCS.
"They all know it's all hands on deck," Maddon said.
