The mock drafts have been all over the board regarding who the San Francisco Giants might select in the first round, and the fact that scouting is being done remotely makes it incredibly difficult to guess who will even be available when the team is on the clock.
Still, there are a few players who will not be available for the Giants by then. Spencer Torkelson, Austin Martin, Emerson Hancock, and Nick Gonzales are just a few of the names who will likely be picked well in advance of the 13th overall spot.
Similarly, my assumption is, the Giants will not be drafting a pitcher in the first round.
