Morse signed a one-year, $6 million contract with the San Francisco Giants for the 2014 season. According to Giants' manager Bruce Bochy, Morse was expected to be San Francisco's everyday left fielder. Morse played at first base for most of May and June after Brandon Belt sustained a thumb injury. On September 2, Morse was diagnosed with a strained oblique and held out of the lineup for the rest of the month, as well as the NL Wild Card game and NLDS.
