The Seattle Mariners (30-30) and the San Diego Padres (28-33) wrap up a 2-game interleague series Wednesday at Petco Park. First pitch is scheduled for 4:10 p.m. ET. 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: Mariners lead 1-0; Mariners won 2022 series 3-1
The Mariners posted a 4-1 victory in Tuesday’s interleague series opener behind RHP Logan Gilbert. The game was still in question until the top of the 8th inning before the M’s tacked on a pair of insurance runs to put a bow on the scoring. OFs Teoscar Hernandez and Julio Rodriguez each had solo home runs and 2-hit games.
The Padres have alternated losses and wins in each of the past 9 games. San Diego’s offense has been limited to a single run in 4 of its last 7 contests, with the Under unsurprisingly going 6-1 during that stretch.

Mariners at Padres picks and predictions
Prediction
Mariners 3, Padres 2
Moneyline
The MARINERS (+100) are a solid play at even money as they look to pull off the 2-game road sweep.
Seattle has won 5 straight games inside the AL West while cashing in 4 of the past 5 interleague games against a right-handed starting pitcher.
The Padres have managed to win just 3 of their last 10 games at home while going 2-5 in the previous 7 vs. righties.
Run line/Against the spread
The Padres +1.5 (-200) will cost you 2 times your potential return if you need a little insurance and do not like them straight up. I know I sure do not.
San Diego is just 1-9 in the past 10 tries in Game 2 of a series and is just 2-7 in the past 9 interleague outings.
PASS.

Over/Under
The UNDER 7.5 (+100) might be the best play on the board in this matinee affair.
The Under cashed on Tuesday, and it is 5-1 in the past 6 for Seattle against NL West foes. The Under is 4 straight against teams with a losing record.
The Under has cashed in 20 of the past 26 games at Petco Park while going 19-6-2 in the previous 27 interleague contests. The Under is also 11-1-1 in the past 13 interleague battles at Petco Park.
