The Seattle Mariners (83-68) will go for a 3-game sweep of the Oakland Athletics (46-105) on on Wednesday afternoon. First pitch at Oakland-Alameda County Coliseum is 3:37 p.m. ET. Let’s analyze BetMGM Sportsbook’s lines around the Mariners vs. Athletics odds and make our expert MLB picks and predictions for the best bets.

Season series: Mariners lead 11-1

Seattle is in a tight 3-team battle for the final 2 Wild Card spots, a race in which they are a game behind the Toronto Blue Jays and tied with the Texas Rangers for the final spot. After losing 7 of 9, they’ve won 2 straight and look for a 3rd before heading into a big weekend series at Texas.

Oakland has dropped 6 straight games and appear destined to finish with the worst record in baseball.

Mariners at Athletics picks and predictions

Prediction

Mariners 6, Athletics 2

Moneyline

Through his recent struggles, Kirby’s skills have held up well, as he boasts a 27/4 K/BB in 27 IP over his last 5 starts. He gets a juicy matchup against an Oakland offense that has really been struggling lately but this line is a little too steep to gamble on. PASS and find better value elsewhere.

Run line/Against the spread

Oakland has scored a league-worst 3.32 runs per game at home this season, and they have scored a total of just 10 runs over their past 6 games. Kirby should get back on track, with a chance to completely shut down his opposition.

Estes will be making his debut against a Seattle team that is 8th in runs per game on the road, and in a fight for their playoff lives. His skills have been pretty mediocre and given the plus odds, MARINERS -2.5 (+110) is worth a small play, or consider moving it to MARINERS -1.5 (-140).

Over/Under

Seattle has had their way with Oakland this year and their bats should have success against Estes. But the A’s have really struggled to score lately and will have their hands full against Kirby. This line appears to be set about right so SKIP the total.
