The buy sign is on with Zac Gallen. He was one of the most promising pitchers in baseball until injuries derailed him. But he's back now and looking great. Just ask the powerful Dodgers. Gallen held LA to one run on three hits in six innings last Saturday in a 7-2 victory. Gallen also was sharp recently against Colorado. He shut the Rockies out on three hits in seven innings with nine strikeouts and only one walk on Aug. 21.

The Diamondbacks are motivated not to finish with the worst record in team history. They are furious about blowing a huge lead to the Rockies on Friday.

Colorado is a terrible road team with a 26-52 away mark.
