Seattle Mariners vs. San Francisco Giants Prediction
I’m on the San Francisco Giants here. I get the allure of backing a team like Seattle in certain spots, but right now for me, the Mariners are a hard team to get behind because of an offense that stalls out far too often for my liking, which was a problem from last year that needed to be addressed, and for Seattle, it wasn’t. The pitching is fine, although it’s weird they have two Luis Castillos on the roster, but at a certain point, last I checked, the rules of baseball are that you have to score more runs than the other team and the pitcher can only do so much. Justin Verlander’s the better arm here and the Giants have gotten off to quite the start at the dish as well this season. I’ll roll with San Francisco in this one.
