Guardians at Cardinals picks and predictions

Prediction

Guardians 5, Cardinals 2

Moneyline

The GUARDIANS (-135) are worth a look as moderate favorites behind the southpaw.

The Cardinals (+115) have managed a respectable 22-19 record against LHP this season, but the problem is Mikolas. St. Louis is 1-3 in his past 4 outings, and 1-3 in his previous 4 assignments at home, too.

The Cards are also just 3-5 in the past 8 Games, while going 1-4 in the past 5 interleague battles at Busch Stadium.

Run line/Against the spread

The GUARDIANS -1.5 (+135) are worth playing lightly on the run line, if you’re a little more adventurous. More risk equals more reward. Cleveland has won 6 of the past 7 games, although 3 of the past 4 wins are by a single run.

As a favorite, the Guardians are 2-4 in the past 6 as a favorite on the run line, so be careful.

Over/Under

UNDER 8 (-115) is the lean, but like the run line above, play this lightly with a half-unit play at most.

For the Cardinals, the Under is on a 5-1 run in the past 6 games, while going 11-3-1 across the previous 15 contests.

As far as the Guardians are concerned, the Under is 15-2-3 in the past 20 games, while cashing low at a 8-1-2 clip in the past 11 outings on the road.
