"It would just be against certain left-handed pitchers, we want to keep his bat in the lineup, like for a day game after a night game, or if he's caught consecutive games," Black said. "Take the load off his feet from catching."
To date, Norris hasn't taken ground balls at first base in pregame drills. But that could happen in the not-so-distant future.
"It would be a gradual build-up of reps. We are working through this," Black said. "But he was an amateur third baseman. He has good hands, good feet and a good baseball mind. This will not happen quick, but we're thinking about it."
Norris has played four innings at first base in his big league career, all in one game in 2013 with the A's.
If the Padres are able to get Norris acclimated to first base and then get him into game at some point, it could give rookie catcher Austin Hedges more opportunities to get into the lineup.
Hedges, recalled Monday from Triple-A El Paso, is expected to get his first Major League start Wednesday as the Padres are playing a day game after a night game.
