At catcher the San Francisco Giants have their franchise player Buster Posey attempting to come back from a hip surgery which will most likely not be fully healed until after the season begins. They also have the promising Aramis Garcia on the roster with Pablo Sandoval, who played the position early in his career and has shown himself willing to do anything to help the team, also available. They clearly need to add an experienced major league catcher who is, ideally, a left hand batter.
Around the infield they have established starters, with expensive hard to move contracts: Evan Longoria at third, Brandon Crawford at short, and Brandon Belt at first, along with the just resigned Joe Panik, coming off a poor season yet still with an upside, manning second base.
