Mariners at Padres picks and predictions
Prediction
Padres 5, Mariners 4
Moneyline
Seattle is 6-12 in its last 18 games; San Diego is 12-6 in its last 18.
The battle of right-handers makes for an advantage for San Diego. The Friars’ .763 OPS against righties ranks 2nd in MLB. The home team is at a bullpen disadvantage in surface stats, especially of late (4.93 ERA since June 1). But expected-ERA figures based on analytics tell a different story, and its likely San Diego’s relief corps is being slightly underplayed by bettors.
TAKE THE PADRES (+115).
Run line/Against the spread
The juice is loose, and with an lean toward a higher-than-projected score, the run line underdog does not bring back enough return here. STEER CLEAR.
Over/Under
The total has gone Over in 10 of Seattle’s last 13 games on the road and in 10 of the Mariners’ last 11 on the road against San Diego.
The Over has also prevailed in 5 of San Diego’s last 6 games in a dozen straight Friars’ games at Petco.
Miller has been prone to louder contact than one might think looking at his ERA. And both Miller and King are fly-ballers pitching on what figures to be a wind-blowing-out game. Mix in the Padres being on their best platoon side, and an 8-plus has enough value.
TAKE THE OVER 7.5 (-115).
