Joey Votto began baseball activities Monday. He threw and took some balls in the field. He's unsure of how close he is to returning to the active list. "It's hard for me to tell," Votto said. "I feel like I've made subtle improvements everyday. But (the medical staff) has a lot of very positive things to say." Votto, who had arthroscopic surgery on his left knee July 17, is running and doing agility drills. "But not at 100 percent," he said.
