Smith will make his spring debut Friday after missing time with elbow inflammation, Patrick Saunders of the Denver Post reports.
Smith's injury was never considered overly serious, but the club decided to take it slow with the southpaw during an extended spring training. Manager Bruce Bochy said he wanted Smith to get in six spring training appearances before the season, and with the 27-year-old back in the lineup, he still has plenty of time to reach that mark. Barring any setbacks, Smith should open the season as the left-handed setup man for the Giants.
