Immediately after the Cardinals and closer Carlos Martinez misplaced a three-run lead in the ninth inning, Carpenter answered with a solo homer to send the Cardinals to a 5-4 victory in the 10th inning Thursday night at Wrigley Field. Carpenter was only in the game at that moment and batting in that spot because Kolten Wong had to leave the game with a left hamstring injury. The severity of the injury was not immediately known as the second baseman continued to undergo tests. The team called him “day to day.” And then his teammates did what they could to take an important stride toward lengthening their season for his return.
