Guess what? The Diamondbacks aren't that bad. They are just one game below .500. If you discount a four-game series against the Dodgers, Arizona would be 10-4 in their last 14 games.

The Diamondbacks are better than the Cubs. They've won the first two games of this series and have the better starting pitcher going here with Madison Bumgarner facing Justin Steele.

So why are the Cubs, losers of three in a row, favored? Got me. I'm just happy to grab this plus price with Arizona.

The Diamondbacks have underrated pitchers and are getting contributions from young hitters. The Cubs are back to rebuilding, eight games below .500. They are 14-38 in their last 52 home games. Chicago has lost eight of the past 11 times when favored.

Bumgarner has a 2.29 ERA. Steele is 1-4 with a 4.50 ERA.
