In this article, we will formulate a Mariners vs Athletics Prediction for this MLB matchup on Friday, September 11th in the opening game of this series. Let’s take a look at the prediction for this MLB matchup.

Athletics Preview


The Athletics have a 59-88 record this season and are sitting in the 4th place of the AL West. They have a 27-45 home record and are coming off a 0-2 home loss against the Blue Jays. They will face the Rays and the Guardians next.

The Athletics have a .245 batting average this season, .318 OBP and .403 Slugging percentage. Oakland’s pitching staff has a 5.35 ERA and 1.49 WHIP. Jeff McNeil is the team’s best hitter with a .268 batting average. Nick Kurtz leads the team in RBI with 69, while Shea Langeliers adds a team-high 23 home runs.

Jeffrey Springs (L) is the projected starting pitcher for the Athletics, and he has a 4-13 record, 6.02 ERA and 1.45 WHIP.

Seattle Mariners Preview


The Seattle Mariners have a 69-78 record this season and are sitting in the 3rd place of the AL West. They have a 29-43 away record and are coming off a 3-4 home loss against the Rangers. They will face the Rockies and the Angels next.

The Seattle Mariners have a .229 batting average this season, .309 OBP and .373 Slugging percentage. Seattle’s pitching staff has a 4.21 ERA and 1.25 WHIP. Randy Arozarena is the team’s best hitter with a .272 batting average, leading the team in RBI with 67, adding a team-high 22 home runs.

George Kirby (R) is the projected starting pitcher for the Mariners, and he has a 9-11 record, 4.18 ERA and 1.34 WHIP.

Mariners vs Athletics Prediction


The Athletics are 3-1 in their last 4 meetings against the Mariners but have lost their last three home meetings.

In this Mariners vs Athletics Prediction, the Mariners are coming as -160 road favorites. I don’t like the pitching in this matchup as both starters have a combined 10.20 ERA and their home/away splits are even worse, with Springs having a 2-9 record and 7.18 home ERA, while Kirby sits on a 5.48 ERA on the road. On top of that, the A’s have the worst bullpen in baseball and both teams are 14-5-1 to the over in their last 20 games combined. Take the over 10 runs in this one.
