Wade will start at first base and hit leadoff in Saturday's game against Oakland, Amy Gutierrez of the Giants' official site reports.
Wade was recalled from Triple-A Sacramento on Friday with Brandon Belt (knee) landing on the injured list. He didn't start Friday against left-hander Sean Manaea, but he'll get the nod Saturday against righty Frankie Montas. Wade could see ample action at first base against right-handers until Belt returns, and he also figures to see time in the outfield.
