Mat Latos (knee) tossed his first bullpen session of the spring on Wednesday in Reds camp. "No stiffness, no pinch," he told reporters after the workout. Latos underwent surgery in early February to repair a tear of the meniscus in his left knee. The Reds are hoping that he won't have to miss a regular-season start, but there remains no set date for the 26-year-old right-hander's Cactus League debut.
