Mariners vs Orioles Prediction

You can talk yourself into the Orioles and the plus money because the Mariners are having a week from hell. However, the Mariners are better than this recent stretch suggests, and at some point they’re going to bounce back. Also, Gilbert has looked good over the last month or so, and the Mariners have won each of his last four starts. It feels like he’s the guy who can stop the bleeding. I’m rolling with the Mariners at home on Tuesday night.
