Are you talking about the club carrying 13 pitchers, including Tim Stauffer? The idea that the Twins will have an overhauled roster a month from now is just... odd and, well, plainly false. That the Twins will regress is the only possible conclusion any knowledgeable observer could draw. OPS for and against gives you the exact same reality of how lucky the Twins have been. BaseRuns takes those hits, walks, etc., and calculates an expected run total, which is more handy than looking at a team's AVG/OBP/SLG slash line.
