The Colorado Rockies are coming from a very impressive three-game sweep of the San Diego Padres over the weekend. It was the only sweep the Rockies have this year against a team not named the Reds and looked very good doing it.

Colorado outscored the Padres 23-11 and are now 5-3 in their last eight games. That’s pretty damn good for a team that’s 11.5 games out of first place in the NL West.

The Rockies head to Miami today to kick off a very winnable three-game series against the fourth-place Marlins. Miami had a rough week and went 2-5 against the Phillies and Mets. Those losses sent them tumbling further down the NL East standings and are now more than a dozen games off the lead. 

Here are the odds for this game with odds from consensus sportsbooks.

Rockies vs. Marlins Prediction and Pick

These two teams may not be the best, but I’ve been very impressed by the Marlins’ starter Daniel Costano so far this year. Castano has seen limited action, with just 10 ⅔ total innings pitched, but I’m still impressed and I’ll tell you why.

Castano has made three appearances from the bullpen and one start this year. One of those relieved appearances was against the Nationals where he pitched two scoreless innings. No big deal there, the Nats suck. But, the remaining 10 ⅓ innings he pitched were all against the heavy-hitting Phillies. Castano has yet to give up a run this year despite three trips to the mound against Philly. This includes a 6 ⅔ inning shutout on Wednesday where he gave up just five hits to a red-hot offense. 

Now, some might argue that the Rockies are a great offense that leads the MLB in batting average, BABIP, and hits per game. And while those people are technically right, they aren’t taking into account that half of the Rockies games are played in the thin air of Denver.

Overall the Rockies are hitting .261 at the plate, but just .237 when they are playing on the road. They have no power outside of Denver either with just 15 home runs on the road compared to 47 at Coors. 

Pick: Marlins -120 to win
