The Giants optioned Teng (oblique) to Triple-A Sacramento on Monday, Susan Slusser of the San Francisco Chronicle reports.
Teng didn't make any Cactus League appearances due to a left oblique strain, but he seems to be just about fully healthy at this point, as he's scheduled to pitch in a minor-league game Wednesday, according to Maria I. Guardado of MLB.com. The 25-year-old right-hander should open the season as a member of Sacramento's rotation.
