Fantasy Baseball Week 17 - RP Under 50% Owned Yahoo

After each week, we will generate a new list of relief pitchers that are less than 50% owned in Yahoo fantasy baseball leagues, with the best K-BB% and an ERA at or below 3.50.

Hopefully this weekly post helps you find some streaming or permanent relief options to help win some pitching categories!

We limited the pool to relievers with at least 40 batters faced and a 20% K-BB%.
