As for what exactly is bothering Edmonds, it's still uncertain.
"It's just irritated," Edmonds said. "I played with it for a couple days and just irritated it more and more and more. I don't know if it has anything to do with this strand of flu that's going around, or it's something else. Now we're just trying to go day-to-day."
Edmonds' spot in center field was taken by So Taguchi, who batted sixth. Moving from sixth to fifth was right fielder Juan Encarnacion. An eight-time Gold Glover and four-time All-Star, Edmonds is batting .243 in 2006 with a .347 on-base percentage and a .382 slugging percentage.
"I hope it will just be a couple days and it will go away," Edmonds said. "It's already been a few days. It's in the lower stomach region, in like the lymphnodes or something, and it's just painful to do anything."
Ponson activated, Duncan optioned: St. Louis activated Sidney Ponson from the 15-day disabled list on Saturday in time for Ponson to make the start against the Padres. Ponson had been out for nearly three weeks with a strained muscle in his right elbow.
Duncan was called up to take the place of Anthony Reyes after Reyes' spot start against Kansas City last week. In four games, he went 1-for-5 with a home run and three RBIs. Duncan has three career hits in 15 big league at-bats, all of them for extra bases.
Carpenter throws: Chris Carpenter took a small step forward as he tries to recover from bursitis below his right shoulder. Carpenter played catch in the outfield, the first time he has thrown since he was scratched from his start on Wednesday in San Francisco.
Nonetheless, the Cardinals are proceeding slowly with their ace. Head athletic trainer Barry Weinberg said that the club will want Carpenter to throw from a mound before he is cleared to play. That will make it difficult for Carpenter to make his next scheduled start, which would be Tuesday at home against Houston. As of now, the Cardinals list Tuesday's starter as TBA.
"We're just going to build him up day by day and see what happens," Weinberg said. "We'll see how each day he recovers and then let them make the baseball decision as to when to put him in."
If Carpenter is scratched, Reyes would be the natural choice to take his spot. The rookie right-hander will be on his regular fifth day on Tuesday.
This date in Cardinals history: On May 27, 1964, the Cardinals lost, 2-1, in a matchup of Hall of Famers. Juan Marichal went the distance for the Giants, striking out 11, while Bob Gibson took the loss despite allowing only five hits over eight innings. Chuck Hiller and Duke Snider opened the game with consecutive solo home runs against Gibson, and that was all the Giants got. But Marichal made it stand up, allowing only a Ken Boyer solo shot.
