Diamondbacks at Rockies picks and predictions

Prediction

Diamondbacks 7, Rockies 4

Even though the Diamondbacks should cruise to a win on the road on Monday, AVOID wagering on the moneyline in this contest.

While taking any team to win by 3 or more runs is risky, it’s  worth taking  DIAMONDBACKS -2.5 (+100) with Kelly expected to start for Arizona. Kelly looked great in his last start vs. the Dodgers before being pulled due to cramps in his leg.

In 4 of their 6 wins against the Rockies this season, the Diamondbacks have won by at least 3 runs.

LEAN UNDER 11.5 (-110).

The Diamondbacks should have no issues producing runs on Flexen in this game, but it’s hard to see the Rockies plating enough runs to hit the Over. Arizona is 2-7-1 to the Over in its last 10 games overall, and the Under is 3-0 in the last 3 meetings.
