Padres vs Cardinals Prediction
The Padres are going to get the benefit of the doubt at home. However, the Cardinals continue to be disrespected in the betting market and you should be taking advantage of it. Only the Rays have earned more money for MLB bettors than the Cardinals. Also, McGreevy has been fantastic with a 2.52 ERA and 0.92 WHIP through 39.1 innings. Canning has just 5 innings under his belt this season. The Cards and the plus money have to be one of the best value plays on Friday’s MLB card.
