His respect for the game keeps him from overlooking an opponent. He's been around long enough to know that anything can happen in baseball, especially during the final weeks of the regular season.
Still, it would be hard to blame the manager if he started thinking about the postseason.
With Monday's 1-0 victory against the Pirates, the D-backs' magic number to clinch the National League West is down to four. The D-backs have not won their division and have not been in the playoffs since 2007.
"Obviously, we all look forward to having the opportunity to experience that," Gibson said. "We know it's not going to come easy, we've known that for the whole season. The Pirates swept us the last time we faced them. They got a ton of new faces there. [Pirates manager] Clint Hurdle's got a ton of options, they're very dangerous, so we just stay focused on that."
On Tuesday, Gibson will send Daniel Hudson to the mound. The Pirates will counter with Charlie Morton.
"Everybody knows what we're up against," Gibson said. "We just prepare, have fun, try and stay loose. We're five games up [Sunday] and the Giants got 10 runs on the board. We're in the second inning, and we're down, 1-0. I said it when we were behind the Giants, you can't worry about the Giants, you just have to push ahead, you just need to take care of your own business because when you start worrying about other people then you get off of what you do."
In his last outing, Hudson allowed just a single in the second inning and two walks after a rough first inning against the Dodgers. He departed following the seventh inning.
As for Morton, he returned to the mound after nine days off in his last start and was much more efficient than he had been recently. Though he walked three, Morton made it through seven innings with 94 pitches and three runs allowed against the Cardinals.
He's won just twice since June 15.
"[The D-backs] have a very good team," Hurdle said. "They have revamped their defense. Their offense has played better. The outfield is very, very solid -- probably as good as any outfield in the Majors as far as defense and offense combined."

The D-backs selected the contract of right-handed pitcher Jarrod Parker from Double-A Mobile and designated infielder Tommy Manzella for assignment Monday.
"The atmosphere is awesome," Parker said. "I just came from Double-A, we won the championship, we celebrated last night. It was a crazy night to find out I'm coming up after a win."
Parker is expected to compete for a spot in the big league rotation next season.
The D-backs are 17-6 in the midst of playing 22 straight games and 28 of their final 31 games against NL West teams.
