Johnson had nothing to do with the win. In fact, he wanted Cahd up instead of Tyler and only switchd because the Cards brought in a lefty. He lucked out.
Actually Davey had a lot to do with that. He forced Matheney to go to his pen for a lesser pitcher figuring the Rook would be less likely to beat him than the vet Tracey. It's all part of the chess match. Davey's chess pieces won today. He gets as much credit for putting the right players in that situation to come through as the player does. That's how it works.
