They swept the Dodgers, lost two of three to the Phillies, split four with the Pirates, won one of three against the Cardinals and looked to sweep the Astros on Sunday.
"We started out very slow in St. Louis, but so far we've salvaged," Gibson said. "Getting the last game [in St. Louis] was big and the way we did it was even better. We've got a tough stretch coming up here. We can't let our guard down."
With ground to make up in the National League West -- the D-backs woke up on Sunday five games back of the Giants and 4 1/2 games back of the Dodgers -- Gibson knows the time to make a move is now.
"Time is of the essence," Gibson said. "We need to certainly win all of our series or average out that way."
After Saturday's game, Gibson thought back to his experience with the 1987 Detroit Tigers, who were 3 1/2 games behind the Blue Jays with eight games remaining. The Tigers surged back to make the postseason.
"You have to have conviction that anything's possible," Gibson said. "We know we've made it hard. Today's the next day. We have to go out and play a good game and beat those guys. Every day after that is just more critical."
The D-backs understand what they need to do to make the postseason: play their best baseball of the season.
"The pressures change everything." Gibson said. "That's the fun part."
