The Seattle Mariners are struggling offensively and look to get the bats moving when they host the Baltimore Orioles on Saturday in the third contest of the four-game set. Seattle has scored one run while losing the first two games of the series and has tallied just four runs during a four-game losing streak. Baltimore first baseman Chris Davis smacked the game-winning homer in Friday's 2-1 victory as the Orioles remained three games ahead of the New York Yankees in the American League East.Nelson Cruz often tormented the Mariners during his stint with the Texas Rangers, and the left fielder did so again with a line-drive homer off Felix Hernandez for Baltimore's first run Friday. Cruz has hit 29 homers this season, second in the majors behind Jose Abreu of the Chicago White Sox. Seattle acquired designated hitter Kendrys Morales from the Minnesota Twins earlier this week, and he drove in the lone run Friday as the Mariners scored two runs or fewer for the 12th time in their last 18 games.TV: 4:10 p.m. ET, MASN2 (Baltimore), ROOT (Seattle)PITCHING MATCHUP: Orioles RH Bud Norris (8-6, 3.78 ERA) vs. Mariners RH Chris Young (8-6, 3.22)Norris has won five of his last six starts, allowing one or fewer earned runs in four of them.
