Athletics vs. Seattle Mariners Prediction

I’m on the Mariners in this one. This is a hefty price for Seattle, but the Athletics have been such a mess and Springs has been a problem in his own right. Kirby is the far better option in this game and has been sharper at home to begin with and I think Seattle gets a much needed win here. Give me the Mariners.
