⚾ Starting Pitchers
Seattle turn to their key man, Logan Gilbert. His 3.65 ERA doesn't make him untouchable, but at home he provides the Mariners with a reliable foundation on the mound. The main challenge will be preventing Baltimore from generating hard contact with runners on base.
Baltimore counter with Brandon Young. His 3.05 ERA is impressive, so the home team shouldn't expect an easy night. However, pitching on the road in Seattle, Young will need to navigate the early innings almost flawlessly-otherwise, the pressure will quickly shift to the bullpen.
Editor’s Prediction
Baltimore are always a threat with their power hitting, but Seattle inspire more confidence in this matchup. The Mariners play at home, boast a more balanced overall game, and send out a starter who’s capable of keeping things under control in the early innings. Young can keep it close, but the Orioles often lose their grip on the road if they don’t get on the board early. If Seattle strike first and carry the lead into the middle innings, the hosts will be in pole position for the win. The editor’s pick - Seattle Mariners to win.
