Seattle Mariners at San Diego Padres odds, picks and predictions

Analyzing Tuesday’s Seattle Mariners at San Diego Padres odds and lines, with MLB expert picks, predictions and best bets.

The Seattle Mariners (29-30) and San Diego Padres (28-32) open up a 2-game set Tuesday at Petco Park. First pitch is at 9:40 p.m. ET (MLB Network). Let’s analyze BetMGM Sportsbook’s lines around the Mariners vs. Padres odds and make our expert MLB picks and predictions for the best bets.

Season series: First meeting; Seattle won the series 3-1 in 2022

Seattle was swept by the Texas Rangers over the weekend and has dropped 5 of its last 6 games. The Mariners gave up a combined 28 runs in the last 2 games in the Texas heat. They are 9-11 over their last 20 outings and have fallen to 10 games out in the AL West.

The Padres continue to be stuck in neutral at 5-5 over the last 10 games. They have really struggled to string together victories at 9-11 and 12-18 over the last 20 and 30 games, respectively. The root of their problem begins offensively, where they are 24th in runs/9 (4.18), 29th in BA (.222) and 23rd in OPS (.696).

Mariners at Padres picks and predictions

Prediction

Padres 5, Mariners 4

Moneyline

In a small sample size, Musgrove has a 7.43 ERA at home over 3 starts as he tries to find his groove following a late start to the season. However, he has given up just 1 ER over 12 1/3 innings across his last 2 starts — both on the road. Meanwhile, Gilbert is coming off a rough start and has yielded at least 2 ER in 8 straight starts and 9 of 11.

The Padres have the edge in the bullpen with the 3rd-best ERA at 3.11 while Seattle is 9th with a 3.68 ERA. This Padres team has to start hitting at some point, and Seattle has lost 4 straight road games.

LEAN PADRES (-135).

Run line/Against the spread

I prefer the Mariners’ side here as they’re 15-12 on the RL on the road, and San Diego is just 13-18 at home. However, I’m not willing to pay -185 for it.

I like the Over in the First 5 here as Gilbert is allowing at least 2 ER in every start, and Musgrove has been shaky at home. Take the OVER 4 TOTAL RUNS FIRST 5 INNINGS (-125).

Over/Under

I like the Over for the full game, too. It’s slated to be a little cool at 64 degrees with an 8 mph gust blowing out to right-center. The Over is 12-3-1 in the last 16 meetings in San Diego and 6-2 in the last 8 meetings overall. I think 7.5 is being too kind to the pitchers Tuesday.

Take the OVER 7.5 (-115).
