Ya know, I hate piling on the manager because end of the day I don't think a manager really moves the needle significantly one way or the other. But it's a 3 run game so not exactly out of reach against a team that's bad on the road, it's the 8th inning and not the 9th, you have an 8 man (7 currently with Diaz day to day) bullpen, it's a close to must win series, it's after an off day where the bullpen is refreshed, and it's the heart of the Cubs order....
and you bring in Chris Mazza. Why.
