One area that stands out for Baltimore is its offensive production. The Orioles have scored more runs, collected more hits, and hit fewer than ten fewer home runs than Seattle despite playing from below .500. The challenge has been on the mound, where the team ERA and WHIP have both lagged behind Seattle's numbers.

Seattle's biggest advantage in this matchup is its pitching staff.

While Baltimore has shown more offensive production, Seattle's pitching gives the Mariners the edge at home.
