Carpenter left Sunday's game against the against the Pirates in the seventh inning after feeling "lightheaded," FOX Sports Midwest reports. It's not clear if the lightheadedness was related to dehydration or some other condition, but Carpenter should be considered day-to-day in advance of Monday's series opener with the Cubs. The third baseman clubbed his fourth homer of the season in the bottom of the fourth inning to give the Cardinals a 1-0 lead prior to his departure.
