What does our offensive production have anything to do with QS's? The only reason Z came out after 5 IP was because of the 9-0 score. A pitcher has to go 6 innings with 3 or fewer runs to get a quality start. I guess next time Lou should tell his players to stop scoring so that Z can chase a meaningless statistic. cubs offense is so selfish JESUS, I was just pointing out a fact No, you weren't. A quality start has to do with the number of runs a pitcher allows, not the number of runs his own team scores. I think he meant that if we didn't have a huge lead, Z would've stayed in the game.
