Mariners at Astros picks and predictions

Prediction

Mariners 5, Astros 3

Moneyline

The MARINERS (+100) are a solid play at even-money in this series finale.

It's a simply reason to take Seattle -- starting pitcher. Miller has been sharp all season, and a strong Braves offense was confounded trying to solve him last time out.

The Astros (-120) are favored despite the fact Brown is going for the home side. He has been atrocious this season, allowing 5 or more runs in 3 of his past 5 starts, while conceding 5 HR in the past 5 starts.

Run line/Against the spread

The Mariners +1.5 (-210) will cost you more than 2 times your potential return, which is way too much risk for not enough reward. If you like Seattle, play it straight up, especially behind one of its best pitchers.

PASS.

Over/Under

UNDER 8.5 (-105) is the lean, but go with a half-unit play at most.

The Under has dominated for both of these teams. The total has gone low in all 6 of Miller's starts, too, while going an amazing 20-2-1 in the past 23 games.

For the Astros, the Under is actually 2-1 in Brown's past 3 assignments, mainly due to a lack of offensive support. The opposition has scored 5 or more runs in each of his 6 starts to date.
