Athletics vs Mariners Prediction
Both teams are tied 5-5 in their last 10 meetings but the Athletics are 3-1 in their last 4 visits in Seattle.
In this Athletics vs Mariners Prediction, the Mariners are coming as -190 home favorites. The A’s have won both games in this series and are still getting undervalued in this spot. Civale is coming off his worst start of the season but Gilbert has been shaky to start the season and has been struggling at home, with a 1-2 record and 4.30 ERA. Civale has been excellent on the road, with a 1.72 ERA and Seattle ranks just 25th in runs per game, so I like the value with the A’s as underdogs in this spot. Take the A’s on the moneyline for plus money.
