Ryan Mountcastle drove in the game’s only run and the Baltimore Orioles pulled out a 1-0 victory to end the Seattle Mariners’ eight-game winning streak on Saturday night.

George Kirby took a no-decision in a masterful start for Seattle, allowing three singles over nine scoreless innings with no walks and seven strikeouts.

Cedric Mullins was placed at second base to start the top of the 10th and stole third. After Anthony Santander grounded out, Mountcastle grounded a pitch from Andres Munoz up the middle to give Baltimore its lone run.

Felix Bautista struck out four in two scoreless innings for the win as the All-Star closer bounced back from his last two appearances, when he gave up five runs in 1 2/3 innings.

The win kept the AL East-leading Orioles two games ahead of Tampa Bay, which rallied to beat Cleveland earlier in the day.

Baltimore starter Cole Irvin worked the first five innings with six strikeouts and four relievers pitched three more scoreless innings before Bautista took over.

The Mariners went 0 for 10 with runners in scoring position and remained one-half game behind Toronto for the third and final AL wild-card spot.

Dodgers win 7th straight

Tony Gonsolin pitched six strong innings and was backed by three home runs as the Los Angeles Dodgers won their season-high seventh in a row, 4-1 over the Colorado Rockies.

Gonsolin allowed a home run to Ezequiel Tovar on the first pitch of the game but kept the Rockies scoreless the rest of the way with only two hits.

He did not walk a batter and struck out six to win his third consecutive start.

Will Smith answered Tovar’s homer with one of his own in the bottom of the first and James Outman and Amed Rosario also went deep for the Dodgers, who have won 11 of 12.

Seager, Garver power red-hot Rangers

Mitch Garver drove in three runs and Corey Seager homered to lead the Texas Rangers to their 10th win in 11 games, 9-3 over the slumping San Francisco Giants.

Garver had a go-ahead single in Texas’ three-run fourth inning and added a two-run single in the ninth.

Seager hit his 20th home run in the first inning and Ezequiel Duran had three hits and a pair of RBIs to help the Rangers improve to 10-1 following a 2-7 stretch.

Michael Conforto and Heliot Ramos homered, but the Giants lost for the sixth time in seven games.
