Angels at Mariners picks and predictions

Prediction

Angels 5, Mariners 4

Moneyline

The ANGELS (+125) did a pretty good job against the Mariners last season, winning 10 of the 19 regular-season meetings while cashing in 6 of 9 games at T-Mobile Park.

The Halos lost in their series opener against the A’s, but L.A. is 5-2 in the past 7 series openers dating back to last season. The Mariners have dropped 4 in a row inside the division dating back to last season, too.

Run line/Against the spread

The ANGELS +1.5 (-165) aren’t priced out of line if you want a little insurance and can’t bring yourself to play the visitors straight up.

However, Detmers was dominant against the Mariners last year and Seattle is just 3-9 in the past 12 series openers despite an Opening Day win.

Over/Under

OVER 7.5 (-105) is worth playing lightly.

The Mariners allowed 6 or more runs in 2 of the past 3 games and cashed the Over in both outings. The Over is also 7-2 in the past 9 meetings between these American League West Division rivals.

The Over is 4-0 in the past 4 road games for the Angels against a right-handed starting pitcher dating to last season, while going 15-7-4 in the past 26 for the Mariners against a left-handed starter.
