The Seattle Mariners (4-6) open a 3-game set with the Chicago Cubs (4-4) Monday. First pitch from Wrigley Field is at 7:40 p.m. ET. Let’s analyze BetMGM Sportsbook’s lines around the Mariners vs. Cubs odds and make our expert MLB picks and predictions for the best bets.
The Mariners lost 7-6 Sunday as -129 favorites at the Cleveland Guardians in 12 innings. Seattle had a 2-run lead with 2 outs in the 9th, but a 2-run double by Cleveland RF Will Brennan sent the game into extras — Brennan also tied it in the 11th with a 1-out, RBI single. Seattle did take 2 of 3 from Cleveland, winning both games as an underdog.
The Cubs are coming off an 8-2 home loss as small -102 underdogs to the Texas Rangers, although Chicago won the series 2-1. The Cubs won the first 2 games 2-0 and 10-3 — both as favorites.
The Cubs and Mariners last faced each other in 2019. Chicago leads the all-time series 13-6, including a current 5-game win streak dating back to July 2016.

Mariners at Cubs picks and predictions
Prediction
Mariners 3, Cubs 2
Moneyline
These teams are opposites in interleague play. The Mariners have won 5 straight on the road, while the Cubs have lost their last 9 at home against a team with a losing record.
The problem is I don’t like Seattle’s line (-155), so I will PASS.
Run line/Against the spread
Seattle is just 2-5 ATS this season as a favorite, and the value of this line is towards the Cubs. You are getting just a little more than even money ATS when picking the Mariners -1.5 (+105) on the road.
I’ll LEAN CUBS +1.5 (-125).

Over/Under
Castillo might be one of the best pitchers in the majors, and I just don’t see much offense in this matchup Monday night.
So far this season, both teams are below the 11.0 league average for homers runs. The Cubs hit 7 and the Mariners have 8.
BET UNDER 9 (-120).
