ST. LOUIS -- Matt Adams and Matt Carpenter spent the afternoon quarantined in Busch Stadium after both woke up with a stomach illness, which manager Mike Matheny said has been making its way around the clubhouse.
The untimely illness kept the two corner infielders out of Saturday's game, too, leaving Matheny to plug the holes at first and third with Yadier Molina and Daniel Descalso, respectively. Matheny wouldn't rule out Adams or Carpenter recovering enough to be available off the bench, though neither was in condition to do so around game time.
Asked if food poisoning could be the issue, Matheny said there were "not symptoms that would go along with that."
The timing of the stomach bug cost Adams the chance to face Reds starter Mike Leake, against whom he's had striking success. In 18 career at-bats against Leake, Adams is 8-for-18 with four doubles. Carpenter's numbers (5-for-23) against the right-hander weren't as notable.
Matheny said that he had been looking for a day to unplug Carpenter from the lineup anyway, sensing that the third baseman was fighting some late-season fatigue. Carpenter is 5-for-27 on this homestand.
"He's still putting the ball in play hard, but as we watch these guys every day, you can see when they're dragging a little bit," Matheny said. "He may have been having a little bit of that [stomach bug] come over him yesterday when he was a little down. Not [down] in effort, but you could see that something was off."
