Unlike the benign conditions at the Arizona Diamondbacks' roofed stadium, San Francisco's AT&T Park will be howling with winds that could give the baseball a push towards center field.
The game-time temperature will be a cool, clear 52 degrees. The 11-mph winds will be blowing from the west-northwest, which will give the ball a push out to slightly right of center field.
Rain will not even be a factor in tonight's game, so brace yourself for a wonderful summer night in the city by the bay.
Tonight, Ryan Vogelsong (1-2, 2.94 ERA) will take on Christian Friedrich (1-0, 1.50 ERA).
