Astros at Mariners picks and predictions
Prediction
Mariners 3, Astros 2
Moneyline
With runs vs. records, both clubs are a little undercooked right now. Both may be decent plays in the near future, but this series likely won’t offer up attractive value sides. Both, however, profile, as getting lesser-than-expected pitching results and slightly better batting results so far. So, the Under figures to be a baseline setting for these 3 games.
STEER CLEAR.
Run line/Against the spread
No interest, focus on the Over/Under for the best value in this one. PASS.

Over/Under
The Under is 6-1 in the last 7 series meetings in Seattle. And 6 straight Castillo outings in series openers have hit the Under.
Both bullpens may be a tad overrated by current surface numbers (both have top-5 ERAs), but both are likely 1st-division units at worst. The stronger of the 2 offenses — Houston — has struggled its way to a .659 OPS against right-handed pitching and is struggling in general over recent games.
With the quality of pitching, the game in a pitchers’ park, and Seattle struggling offensively at home, BACK THE UNDER 7 (-120).
