The only problem I have with this research is that it has elements of a chicken-and-egg set of results. Marquis' starts factor into those depressed numbers, so you can legitimately ask whether it's the cause or the effect. But Marquis' starts aside, in general all those teams with the worst offenses you cited have faced very good pitching for up to half the games played this year: -St. Louis has 15 games against Cubs, Brewers, Mets -Pitt. has 14 games against Cubs, Brewers, Dodgers -SD has faced Chicago and LA -Hou and Cin. both have faced Chicago and Milwaukee All of these teams have faced top 5 NL (Mets, Dodgers, Brewers, Cubs, Padres) pitching numerous times. Now I don't think anyone expects Marquis to keep this up, but Marquis' deserves credit for those starts he has sparkled in thus far this year.
