I'd say that you are ignoring common sense, which says that different guys will react differently to being up by many runs. Some guys may relax more in an 8-0 game which may cause them to throw BETTER than they would in a 1-0 game. Some guys may lose focus because of the big lead. Some guys may purposely throw more strikes to avoid walking batters which may cause more line drives and hits OR may cause more quick innings which would allow the pitcher to go deeper into the game and again put up better stats than he normally would. On the whole (taking everybody's statistics and lumping them together), you see nothing--perhaps because all of these factors cancel each other out, or perhaps because there is nothing there to see. As Russ said in the other thread, an absence of evidence is not evidence of absence; particularly when trying to use stats from ALL players to say that ONE particular player isn't affected by circumstances. It's just extremely poor use of stats. In 2010 Marcum's ERA declined with the amount of runs the Jays scored. Its random. Yes Marcum has pitched better away from Miller Park but there is no reason to expect that to continue. You have a 50 point swing in BABIP and a strand rate of 82% when he is away.
