"They will try everything to play this game," Feeney said. "It would have to be a pretty torrential and long-term rain to affect us. You would almost have to have hurricane weather."
MLB controls decisions about weather-related issues during the postseason, and Joe Torre, executive vice president for on-field operations, is on site. Officials consider the forecast as well as the condition of the field in making the call.
The latter consideration is much less of an issue these days, given the tremendous improvements in drainage systems that have accompanied new ballparks across the game.
Rain already has affected this NLCS. Game 3 in St. Louis was interrupted for nearly 3 1/2 hours in the seventh inning by a wave of storms.
Cards starter Kyle Lohse said he wouldn't be surprised if Mother Nature makes another appearance on Monday.
"We have kind of a joke in the clubhouse -- it seems like probably 60 percent of my starts have rain in the forecast," Lohse said. "It's not going to change anything. My last start against [the Giants], rain was in the forecast. Nothing really changes my approach or my mentality going into it. If it rains and we get delayed, I've got more time to hang out in the clubhouse. There's not a lot I can do about that."
If either starter sees his start interrupted by the weather, both teams have capable replacements in waiting. Tim Lincecum is available for the Giants, manager Bruce Bochy said, and Adam Wainwright will be available for the Cardinals.
If Game 7 does get pushed to Tuesday -- a scheduled workout day ahead of the World Series -- then the Cards could consider starting Wainwright, who delivered seven outstanding innings in Game 4 on Thursday.
But that seems unlikely, considering Lohse was St. Louis' most consistent starter throughout the season and manager Mike Matheny's choice to start the Wild Card game against the Braves and Game 1 of this series.
Asked about the potential for him pitching in Game 7, whether or not the weather plays a role, Wainwright said, "I'll be ready to cheer first, and hopefully, they don't need me. I'd love to see Kyle go out there and dominate that game, and we have very capable relievers as it is.
"So I expect to not pitch [on Monday], but I'll be ready if they need me."
