Athletics vs Mariners Prediction
The Mariners are still having issues finding their footing and I’m not trying to do this song and dance with them. Castillo has been awful this season and that includes allowing 16 hits and 13 runs in his last 18 innings. In 23.2 road innings, Castillo has a 6.85 ERA and .290 allowed batting average. The A’s have found their offense over the last couple of weeks, and Civale has a 3.33 ERA and 1.39 WHIP on the season. The Athletics are 4-0 this month under Civale, and he’s allowed just 8 runs in his last 26 innings. I’m rolling with the Athletics at home.
