Mariners at Athletics picks and predictions


Athletics 5 Mariners 4

Money line

The Mariners have lost 4 straight series openers. It’s tough to go all-in on Sears right about now but consider an Oakland play if the tag hits +185 or better. Otherwise STEER CLEAR.

Run line/Against the spread

PASS: Would rather chance the bigger payday on the Oakland ML.


Castillo has the tendency of struggling a bit in the back half of 2 straight starts on the road and these A’s had him clocked the first time they faced him.

Both Castillo and Sears have their numbers tamped down a bit by some generous clutch pitching results.

Some 2-sided regression and a batter’s breeze in the forecast is enough to tilt this one off its 6.5-run axis TAKE OVER 6.5 (-135).
