San Francisco Giants catcher Joey Bart was placed on the 10-day injured list Sunday with a strain in the middle of his back. The move was made retroactive to March 31, and the team recalled right-handed reliever Sean Hjelle from Triple-A Sacramento before its series finale against the New York Yankees. Bart was scratched from the lineup Saturday with back tightness, and manager Gabe Kapler said a scan showed a "very small" mid-back strain.
