Smith (elbow) is progressing well from the elbow inflammation he experienced earlier in camp. He threw to hitters Monday, and could make his Cactus League debut as early as Friday, the San Francisco Chronicle reports.
Manager Bruce Bochy said that he wanted to give Smith six spring training appearances, and there is still plenty of time left for him to stick to his original plan. Assuming he doesn't suffer a setback, the southpaw will open the year as the Giants left-handed setup man.
