According to the National Weather Service, weather conditions are expected to remain wet and unchanged for most of Wednesday, with potential for a slight break in cloud cover occurring around 7:00 pm MT, approximately 30 minutes after the scheduled first pitch of 6:40 p.m. MT.
The scheduled starters features a matchup of veteran lefties. The Giants' Tim Lincecum (8-14, 5.11) would face off against Colorado's Jeff Francis (5-4, 5.38).
If weather prevents the game from commencing, the game would likely be moved to Thursday, September 13. Both teams have a scheduled travel day that could be replaced with a make-up game instead. This is the last time that San Francisco visits Coors Field for the season, so there is plenty of incentive to finish the series this week.
