I am looking for statistics on either ERA or runs scored by month (or graphically, by date). I am looking for evidence that playing more starting pitchers at certain times of the year (especially April-May) can help my team's ERA/Whip. If it holds true that fewer runs are scored early in the year, and possibly late in the year as well, then I can strategize accordingly, using more of my innings during those times and less during months when hitters are coming out ahead. Anyone know where I can find such statistics?
Please help with my keepers:
