"This game is about adjustments, whether you're a player, coach or manager," Bochy said. "We might have to make adjustments in that area -- which guys we'll go to early, bringing Petit and Lincecum into that mix even though they haven't done it earlier."
The right-handers' ineffectiveness weren't isolated instances. Relied upon primarily to pitch the sixth or seventh inning or neutralize right-handed batters, Machi has been scored upon in three of his last four appearances.
"He probably has lost a little bit of confidence, to be honest," Bochy said.
Strickland, a rookie who has been celebrated for his ability to throw 100 mph fastballs, has recorded a victory and a save during the postseason but also has allowed five home runs in six appearances.
Bochy maintained his faith in Machi, who led the Giants with 71 regular-season appearances, and Strickland, who impressed the Giants by striking out Washington's Ian Desmond with the bases loaded in the Division Series opener.
"I think you've got to stay behind these guys," Bochy said. "They need to know it. So I'm not going to sit here and say, 'No, I will not use him in a high-stress situation.'" However, Bochy hastened to reiterate that he might "tweak" how he deploys Machi or Strickland "to get [them] back on track."
Their erratic performances prompted Bochy to ponder expanding the roles of Affeldt, Casilla, Petit, Romo and even Lincecum, who left Game 2 with back stiffness but returned Friday feeling fit after undergoing a clean MRI.
Lincecum logged 1 2/3 scoreless innings in Game 2 despite not having pitched all postseason, which Bochy said gave him "a little sense of comfort" about using the two-time Cy Young Award winner in what remains a relatively unfamiliar role for him.
