George Kirby pitched seven three-hit innings, and the Seattle Mariners beat the Baltimore Orioles 1-0 on Tuesday night for their eighth victory in a row. Josh Naylor’s RBI single in the first inning was all the scoring the Mariners needed. Eduard Bazardo and Gabe Speier worked the eighth, and Andrés Muñoz labored through the ninth for his 28th save in 34 chances.
