Romo and Lopez combined for a scoreless eighth and ninth inning, with Lopez notching his third save in the last week.
"I think we can juggle it the whole way," Bochy said. "Ideally, you have one guy, but I think that they enjoy knowing that really any of them can be out there in the eighth or ninth. It keeps them on their toes a little bit. Whether we change to one guy, I can't say right now, but for at least the near future, we're going to continue to match it up."
Romo left after getting two outs in the eighth and was showing some discomfort with his right arm, and Bochy said after the game that Romo may have been bothered by a tight hamstring. Bochy said before Saturday's game that Romo was fine physically but that he would be giving him the day off.
"Serg can be a hard read sometimes," Bochy said. "Sometimes he doesn't open up all the way about what's going on. When he got to the dugout, he said, from what I hear, his hamstring was a little tight."
