BALTIMORE — Jackson Holliday hit his third career grand slam, Brandon Young pitched seven scoreless innings and the Baltimore Orioles beat the Seattle Mariners 7-2 on Wednesday night to snap a four-game losing streak.
Holliday became the first player in franchise history with three grand slams before turning 23. The 22-year-old infielder has 25 major league home runs.
Young (5-1) gave up two hits, walked two and struck out five. Baltimore is 9-1 in games started by Young this season.
Pete Alonso hit a solo homer and singled, and Leody Taveras went 2 for 3 with an RBI double.
Alonso's leadoff drive in the sixth opened the scoring. Colter Cowser walked four pitches later, stole second base and scored on a double by Taveras, who then stole third before Blaze Alexander hit a ground-rule double with two outs that made it 3-0.
Holliday's slam extended it to 7-0 in the seventh before Seattle got two runs in the eighth. Miles Mastrobuoni scored on a groundout by Julio Rodríguez, and Josh Naylor singled home Patrick Wisdom.
Seattle starter George Kirby (5-6) allowed three runs and seven hits in six innings. He walked three and finished with a season-high 10 strikeouts.

Seattle went into the game an MLB-best 11-3 (.786) since May 25.
