Marlins at Diamondbacks picks and predictions


Diamondbacks 5, Marlins 4

Money line

The Marlins are struggling right now. They were swept by Arizona in Miami last week and have only 1 win in their last 8 games. They are 7-8 this season on the road.

The Diamondbacks’ starting pitching has been carrying them. They have won 9 of their last 12 games behind the league’s No. 2 starting pitching ERA at 2.21.

The Marlins have scored 2 or fewer runs in 3 of their last 4 contests.


Run line/Against the spread

The Diamondbacks have MLB’s second-best record against the spread overall this season. They are 18-11 ATS, trailing only the Los Angeles Dodgers at 19-7 ATS. They are 16-10 ATS as underdogs.

The Marlins are 15-13 ATS but only 4-10 ATS as favorites.

It is close to being too pricy to be worth a bet but take the DIAMONDBACKS +1.5 (-170).


All 3 games had totals of 9 or more runs in their 3-game series in Miami last week.

Both teams have been in low-scoring games recently. The Marlins haven’t had a game with more than 8 runs in their last 4 outings and the Diamondbacks have not surpassed that number in their last 3 contests.

Castellanos has not pitched more than 5 2/3 innings in any out this season and Arizona’s bullpen ERA is 4.71, the 4th highest in the majors.

Take OVER 8.5 (-112).
