Padres at Mariners picks and predictions

Prediction

Mariners 6, Padres 3

Moneyline

The MARINERS (-145) are a strong play at home behind Gilbert. While he has had some issues keeping the ball inside the park at home, conceding 11 homers in 58 innings across 10 starts, he can be trusted here.

Gilbert allowed just a single run on 3 hits with 2 walks across 7 innings in a 4-1 win on June 6 in San Diego. Look for him to handcuff the Padres again.

Run line/Against the spread

The MARINERS -1.5 (+140) are worth a look against the skidding Padres.

Seattle is 4-1 in the past 5 games as a favorite while San Diego is 7-7 in the past 14 outings on the run line as an underdog. While the Padres did win outright as an underdog in San Diego against Seattle on June 7, it lost by 3 runs against Gilbert and the M’s in the season-series opener on June 6.

Over/Under

OVER 8.5 (-110) is the lean, but play it very lightly.

The Over-Under has split in the first 2 games this season while going 3-1 in the past 4 meetings overall.

While the Padres have cashed the Over in 4 in a row, the Under has cashed in Seattle’s last 2 outings and is 5-4-1 in its last 10 games overall.
