George Kirby, M’s edge Orioles 1-0 for 8th straight win

Seattle’s George Kirby held the host Baltimore Orioles to three hits in seven innings and the Mariners won 1-0 for their eighth consecutive victory in a classic pitchers’ duel Tuesday night.
Kirby (8-5) struck out seven without a walk, facing just two batters over the minimum during his stint. He has won four straight starts and he now has at least eight wins in each of his four major league seasons.
Relievers Eduard Bazardo, Gabe Speier and Andres Munoz completed the five-hitter.
Munoz secured his 28th save despite issuing a two-out walk to Gunnar Henderson in the ninth and then a single by Adley Rutschman. Ryan Mountcastle grounded out to end the game.
Baltimore’s Dean Kremer (8-9) was the hard-luck loser after tossing eight innings of one-run ball. He allowed five hits and one walk while striking out six. Rico Garcia pitched a scoreless ninth.
A first-inning run held up as the Mariners won for the 10th time in 11 games.
Randy Arozarena opened the game with a single and stole second base with one out. Josh Naylor delivered a two-out single to drive in the game’s lone run.
Baltimore, which took its third loss in a row, stranded five runners on base, two more than the Mariners.
The Orioles have been shutout victims three times this month, including a 1-0 decision to the Cubs in Chicago on Aug. 1.
Kirby cruised for three innings with the exception of Dylan Carlson’s one-out infield single in the third inning. Greg Allen, the next batter, grounded into a double play.
Henderson hit a two-out double in the fourth for the game’s only extra-base hit.
Baltimore’s Ryan Noda singled with one out in the eighth, but Bazardo struck out Carlson, and Speier got pinch hitter Jeremiah Jackson to line out to center field.
No player in the game had more than one hit. Baltimore has a total of 17 hits in its past four games.
