Gunnar Henderson's leadoff homer launches big 1st inning for Orioles in 9-2 win over Mariners

Gunnar Henderson's fourth leadoff homer of the season sparked a five-run first inning that backed an effective pitching performance by John Means and carried the Baltimore Orioles past the Seattle Mariners 9-2 Friday night. After Henderson's 13th home run — tied for the major league lead — Baltimore's next five batters reached base against Bryce Miller (3-4). A throwing error by shortstop Dylan Moore let in a run and Colton Cowser followed a walk with a two-run double down the right-field line.
