Cardinals pitcher Brad Penny hit a grand slam in the third inning on Friday night against the Angels. However, he aggravated an upper back injury he suffered the previous start and had to leave the game. St. Louis defeated Los Angeles 9-5. The Cardinals were unsure of the severity of the injury and scheduled an MRI exam for Saturday morning. "It was something I was trying to deal with between starts," Penny said. "I couldn't have pitched that last inning, there was no way. The first inning, I felt incredible. The second inning, I felt OK and the third inning, I started feeling a little worse."
