St. Louis Cardinals vs. San Diego Padres Prediction
I’m on the Cardinals in this one. I get the case to be made for the Padres as Vasquez has been a solid arm for this Padres rotation all season long. However, the Padres just continue to be hit or miss and the Cardinals aren’t a team I’m looking to step in front of right now. Give me St. Louis.
