"Around here, we take a lot of pride in [the] team. We take a lot of pride in how your teammates perceive you," Matheny said. "I've been doing it really trying to help him with how he's perceived by his teammates, and he's been conscious of it. … I'm not asking any of these guys to be choir boys. But I do care very much how they're teammates and how they all get along and the chemistry.
"If he's got to be angry out there [to be successful], then I want him to be the angriest man on the planet. But keep in mind that there are some things that you need to do as far as your teammates are concerned. So let's continue to work on this to figure out how you can keep that intensity, have that emotion, but not in a way where you're perceived by your teammates negatively."
Matheny sees Lynn's biggest challenge as finding the middle ground between maintaining the intensity that has made him baseball's winningest pitcher since the start of last season, and harnessing it to the appropriate degree. On Saturday, Lynn's attempts to curb his emotions resulted in him slowing down the game to a sluggish pace.
"I think yesterday when things didn't go his way, he was trying to keep himself from exploding, and in the meanwhile it slowed down the pace of the game and it came across as bad poise on the mound," Matheny said. "We lose sight that he is a young pitcher. But he's a very young, talented pitcher. We're just trying to communicate in a way that can help him in his career."
These same two issues of intensity and body language were addressed with Lynn last season, and before Saturday, he had seemingly been doing a better job keeping both in check this year. What the Cardinals want to be careful not to do, however, is sap the emotion out of Lynn completely, as it has long been a driving force behind his success.
"He's so intense; a lot like a [Chris] Carpenter," Matheny said. "And if Carp would have done early in his career a lot of things that he did later in his career, he would have had a lot of people talking to him. You can't sit out there screaming at people. That's just part of the learning curve. But you also realize, like we're realizing right now talking to him, that some of that is a part of your greatness. Let's try to nurture that but chip away the things that happen in here."
Matheny emphasized that such one-on-one conversations with a player happen almost daily inside the Cardinals' clubhouse. A day before, it was rookie reliever Carlos Martinez, who heard from Matheny and other veteran teammates after his rough outing on Friday.
"This stuff constantly happens on a good team," Matheny said. "On a bad team, the veterans let the young guys do what they want to and the young guys run amok. You don't see everybody coming together to try and help each other out."
