It's do or die for the Arizona Diamondbacks' playoff run. In this five-game National League Division Series, the D-backs are down 2 - 0.

The D-backs must win this game to keep our playoffs dreams alive. The upside is this game, unlike the first two, are on our home turf.

And ace Zack Greinke will be taking the hill for Arizona, hoping to bounce back from an uneven performance in the wild card game. Greinke started strong for the D-backs last Wednesday against Colorado, but gave up four runs in the fourth inning, letting the Rockies back into the game before getting the hook.

Meanwhile, midseason acquisition Yu Darvish is the Dodgers' starting pitcher. The former Texas Rangers top man has slid into the second spot in the LA rotation, and after a bumpy start to the year in Arlington, he's pitched better in Dodger blue, bringing his earned-run average below 4 on the year and striking out more than 11 batters per nine innings.
