The winds will slightly shift westward, which will carry the baseball out toward straightaway center field for tonight's contest between the Colorado Rockies and the San Francisco Giants.
The game-time temperature will be a cool, calm 54 degrees. According to Christina Loren's weather report, there will be no chance of rain.
The west wind at 11 mph will push the ball straight out towards center field. This will close the right-center field gap a bit, but the wind could help Tim Lincecum tonight, who is a fly-ball pitcher.
Tonight, Tim Lincecum (2-3, 5.89 ERA) will take on the Rockies' Jeremy Guthrie (2-1, 5.92 ERA). Looking solely at the ERAs, offense could be a-plenty tonight at the ballpark.
