DENVER -- When they walked into the visiting clubhouse Sunday following a 13-4 win over the Rockies, there was a brief moment when the D-backs thought about putting the Dodgers-Giants game on television.

It was quickly decided that was not a good idea.

"The question came up, 'Do we dare turn on the Dodgers game?'" catcher Chris Snyder said. "No. We took care of our part. That's all we can do. We did what we needed to do and that's what we have to keep doing."

In other words, put away the calculator, the magic number for the Dodgers does not matter any longer.

And while you're at it, stop that scoreboard watching and focus on the game at hand.

That's the approach the D-backs are taking as they enter the final week of the 2008 season trailing the Dodgers by 2 1/2 games. The D-backs have seven games left, four against the Cardinals at Busch Stadium and three at home vs. the Rockies.

The Dodgers, meanwhile, play host to the Padres for three following an off-day Monday and then wind up the season with a three-game set against the Giants at AT&T Park.

"Last year we were ahead at this point. This year we're behind, but it's still a lot of fun to be in the race," outfielder Chris Young said. "A lot of teams would give a lot to be in our position right now no matter how long the shot is. We do have a chance and we'll see what happens."

And the math gets more daunting by the day.

"You try to win that particular day and at the end we'll add them all up," D-backs manager Bob Melvin said. "We know we've got a significant road ahead of us still. We have to keep putting pressure on and winning games. You can't win three games in a day and you can't look ahead at all. You just have to keep grinding."

Unlike last year, the D-backs don't control their own destiny, thanks to a miserable stretch at the end of August and beginning of September that saw them go from 4 1/2 games up on the Dodgers to 4 1/2 back.

Even if the D-backs win out, they will still need the Dodgers to lose.

"Hopefully we get some help on the other side because we need it," Melvin said. "But we realize that every game we go out there is a must-win for us."

A month ago when pundits handicapped the season's final week, it seemed to be a tough one for the D-backs with four games against the Cardinals, who were battling for a playoff spot at the time.

St. Louis, though, has fallen on hard times and dropped from postseason contention. The Cardinals have lost nine of their last 11.

While it's certainly tougher to sweep a four-game series rather than a three-game set, the D-backs do have some recent history to draw on, having beaten the Giants four straight last week at Chase Field.

"Anytime you go into St. Louis -- especially for four games -- it's difficult," Melvin said. "We try not to get too far ahead, just take it day-to-day and try to win every game and then move on to the next day."

The D-backs took two of three from the Cardinals earlier this month at Chase Field, and Arizona has had its way with the Rockies, winning 12 of 15 meetings against their division rivals this year.

"Forget the scoreboard watching," Snyder said. "We've got to win. That's it. Whatever happens at the end of the season if we lay it all out there, then so be it."
