If Evan Marshall, who was called up from Triple-A Reno this past week, continues to pitch well he could see some action in the seventh.
"Guys are understanding their roles a little better, we're getting guys slotted in," Gibson said. "Before we were throwing guys by necessity, where now it's more organized because we're getting better starting pitching."
• Gibson toyed with the idea of playing Eric Chavez at first base and using Paul Goldschmidt at designated hitter this weekend as a way of giving Goldschmidt a little break.
After thinking it over, though, Gibson decided not to press the issue with Chavez's knees, which can act up at times.
As for Goldschmidt not yet receiving a day off, Gibson said none is planned for him anytime soon.
"Goldy, you just kind of monitor," Gibson said. "There's things that you watch and you have the injury report where guys get nagging things and Goldy really hasn't had any of that."
