I haven't heard the talking heads mention this yet, but it appears to me one of the most significant reasons for the cards being up 3-1 is their young arms in the bullpen. Ironically, it was supposed to be the Detroit young pen flamethrowers that were to dominate this series, but instead the dominance is coming from the Cards young hurlers. For example, if you look at the Cards Adam Wainwright, Tyler Johnson, Randy Flores, and Josh Kinney, you will find the following....

28 IP, 1 ER...that is, a 0.32 ERA
3 Wins, 0 Losses, 3 Saves
opposing batters are hitting .179
36 K's, 8 BB's

These 4 guys have been STUDS!
