Seattle Mariners at Los Angeles Angels odds, picks and predictions

Analyzing Friday’s Seattle Mariners at Los Angeles Angels odds and lines, with expert MLB picks, predictions and best bets.

The Seattle Mariners (30-31) and the Los Angeles Angels (34-30) kick off a 3-game series Friday at Angel Stadium. First pitch is scheduled for 9:38 p.m. ET (Apple TV+). Let’s analyze BetMGM Sportsbook’s lines around the Mariners vs. Angels odds and make our expert MLB picks and predictions for the best bets.

Season series: Angels lead 2-1

Mariners pitching has been horrendous lately, coughing up 10 or more runs in 3 of the past 4 outings — and 6 times since May 26. It’s a little surprising too, as Seattle still ranks 12th in the majors with a 4.02 team ERA while checking in with the 6th best WHIP at 1.22.

The Angels have picked up 4 straight victories, averaging 4.5 runs and allowing 2.0 runs per game. It’s no surprise that the Under is 3-1 during the impressive span.

Los Angeles won 2 of 3 meetings when these divisional rivals squared off in Seattle on April 3-5. Seattle’s lone victory was an 11-2 rout in the middle contest as it outscored L.A. 17-13 in the series.

Mariners at Angels picks and predictions

Prediction

Angels 5, Mariners 2

Moneyline

The ANGELS (-135) are a solid play at home in this series opener with Ohtani on the bump.

Ohtani has already beaten the Mariners once this season, allowing just 1 ER, 3 H and 4 BB with 8 K across 6 IP to earn his 1st victory of 2023 on April 5.

The Halos have won 5 of the past 7 meetings in this series, are 7-3 in their last 10 games overall and have cashed 9 of the past 11 series openers.

Run line/Against the spread

The ANGELS -1.5 (+155) are worth a roll of the dice on the run line behind Ohtani.

The Mariners have been hemorrhaging runs lately, going 1-4 in the past 5 games as underdogs on the run line and losing by 7 or more runs in each of their past 3 losses.

Over/Under

The total is very low, but that’s the ‘Ohtani Factor’. When he is on the bump, the shops adjust accordingly. I actually expect the total to come right in on the number, but if I had a lean, it would be to go lightly on the Over.

The best play is to AVOID, and just focus on the moneyline and/or run line.
