Mariners at A’s picks and predictions

Prediction

Mariners 4, A’s 3

Moneyline

The MARINERS (-144) are a solid play as moderate favorites in the series opener. Gilbert has been pitching well all season, including a solid 3.81 ERA and 1.00 WHIP on the road.

The Mariners are a respectable 5-4 in 9 games under interim manager Dan Wilson, and the schedule is set up for Seattle to make a move still, but it needs to get going.

Run line/Against the spread

If you’re a little more conservative of a bettor, A’S +1.5 (-144) is worth playing lightly behind Bido. He has really come into his own for Oakland, posting a 3.03 ERA at home this season and holding the opposition to a .188 batting average. This will be a surprisingly decent pitching matchup.

Over/Under

UNDER 7.5 (-112) is the lean, but go with a half-unit play at best.

While the Over is 6-3-1 across the past 10 games for the Mariners, the Under cashed in each outing of the previous 3-game set in Oakland.

For the A’s, while the Over is 4-1 in the past 5 outings, the Under is 9-6 across the past 15 games. And the Under has cashed in 4 of the past 5 outings by Bido.
