The Dodgers are hopeful to use only those two pitchers, who are not expected to make the Opening Day roster, and save everybody else for the season-opening weekend series with the D-backs.
Because MLB rules allowed only five extra players to make the trip, some of the players from Thursday's game will be on the active roster Saturday, but Mattingly said he will keep their usage to a minimum.
Miguel Rojas, Alex Guerrero and Joc Pederson will likely play the entire game, as they are not likely to be on the active roster. In that scenario, the Dodgers would carry three catchers, including Drew Butera, who is out of options.
