Giants vs Cardinals Prediction

This is a big series as the Cardinals and Giants are fighting for a wild card spot. I’m siding with the Giants on Tuesday. Pallante has been hittable all season with his 5.29 ERA and 1.44 WHIP, and the Cardinals have lost 8 of his last 9 starts. As I’ve said many times before, Webb is great at Oracle, where he has a 2.85 ERA and 1.13 WHIP through 536 innings. Webb has a 60.3 percent winning percentage at Oracle through 85 starts. We’ve made nice coin over the years backing Webb at home. It should be no different in a big spot to keep playoff hopes alive. Give me the Giants. Of course, I’ll lay the RL to shave down the juice.
