Pitcher with much worse ERA is a very good bet. This is a clear regression to the mean angle to the tune of +330 units. Yes it is in a mini-slump right now as all great angles will go in eventually. No worries, it will explode likely today. A solid bounceback angle has an ROI if 6.7 percent also applies to Boston. An IL angle is +152. 82. When the two high volume angles both apply, it has an ROI of 13.3 percent.
