The only real sense of panic in the Cubs' bullpen these days comes when the phone rings and they can't hear what name is being called on.
Apparently there's some issues deciphering between "Rodney" (Fernando Rodney) and "Ronnie" (Hector Rondon).
That's about as high stress as it gets down in a bullpen that can be seen joking around with fans or stomping around and clapping when Starlin Castro's walk-up song comes on.
"I think a lot of it is just, there's no pressure on anybody because there's so much depth," said Trevor Cahill, who got the win in the NLDS-clinching Game 4 after pitching the sixth inning. "There's not really roles in the bullpen.
"[The fourth inning] is just as important as the eighth or ninth. [Manager Joe Maddon] realizes that and he knows the game is decided every inning, not just the eighth or ninth."
Cahill talked a lot about Justin Grimm's performance in the fourth inning, crediting the Cubs "mid-innings closer" (as Maddon tabbed Grimm earlier in the season) with saving the game for the team. Grimm entered after a leadoff walk by Jason Hammel and the first batter immediately reached on an error by third baseman Kris Bryant.
But Grimm buckled down and struck out the next three batters in succession, pumping his fist and setting the tone for the bullpen.
Maddon emptied out his entire bullpen, utilizing seven relievers to shut down the Cardinals for six innings. They allowed two runs on five hits and a walk, striking out 13 batters.
"The bullpen was fabulous," Maddon said. "Grimmer really set the tone. ... From the beginning to the end, the bullpen was fabulous."
In the four-game series with the Cardinals, the Cubs relief corps boasted a 3.14 ERA, racking up 21 strikeouts to only one walk in 14.1 innings while picking up two wins, eight holds and a pair of saves.
How have they been able to find such success?
Well, one of Maddon's favorite phrases - "Do simple better" - has come into play.
"We try to be simple," Rondon said. "When we come into the game, we try to make a pitch. We don't try to do too much.
"I know the adrenaline gets ramped up, but we still have to make those pitches. We did a really good job today."
Maddon has spent all year building this "egoless" bullpen, not assigning any true roles to anybody and even moving Rondon (who finished the regular season with a 1.67 ERA and 30 saves) out of the unofficial closer's role at one point early in the season.
"We never know [when we are gonna go in] and I think that helps us," Cahill said. "Nobody's too relaxed. We're always good to go. We're always loose and stretched out.
"Guys say they like the routine or roles or whatever, but other than Ronnie, we just go out there and we're ready to go whenever the phone rings."
Maddon has been putting his guys in situations all year to prepare them for the playoffs, cranking the intensity up in moments like the series against the San Francisco Giants Aug. 9 when Rondon loaded the bases with nobody out and struck out the next three hitters to close out a four-game sweep.
"We absolutely learned from [situations like that]," Rondon said. "That helped us to be better and to learn to control ourselves."

The crazy thing about the Cubs bullpen is how it was constructed. Only Grimm, Pedro Strop and Rondon began the season in the bullpen.
Travis Wood started the year in the rotation while the other three - Clayton Richard, Rodney and Cahill - were all designated for assignment by other MLB teams.
The Cubs picked them up off the scrap heap and formed a bullpen that plays in October.
"It does say a lot, the fact that you sometimes have to look underneath some stones, turn them over and see what's underneath there," Maddon said. "You have to research a little bit more deeply and find out."
After all, who thought two months ago that Cahill would be getting the win and Richard and Rodney would garner holds in the game that clinched the NLDS for the Cubs?
