Giving the quality of pitching, the Phillies-Cardinals opener is unlikely to be a slug fest.
But nature is going to give the hitters exactly what they don't need. It's going to side with the pitchers.
At game time, temperatures will be in the upper 50s with a healthy 12 m.p.h. wind blowing in from left field.
That breeze should persist throughout the game, and those aerodynamics would work against the flight of fly balls.
