Shane’s Free Pick

It’s kind of stated above, but this game is going to be a pitchers duel. Kelly sits with an ERA of 3.12 while Castillo sits with an ERA of 3.02. Both of these offenses are going to really struggle to get any sort of offense going here, and that will lead to this game being lower scoring. Back the under to cash here with ease.
