Romero's first career HR helps Mariners edge A's

Oakland, CA (SportsNetwork.com) - Stefen Romero stroked his first career homer and scored twice to help the Seattle Mariners secure a 4-2 win over the Oakland Athletics in the opener of a four-game set Monday at O.co Coliseum.

Romero's solo shot in the fifth snapped a 2-2 tie, while Brad Miller, Kyle Seager and Corey Hart each added an RBI in support of starter Chris Young (2-0), who held Oakland to two runs on three hits and two walks over six-plus innings.

Five Seattle relievers combined to keep the A's off the board from there, culminating in a perfect ninth inning from closer Fernando Rodney, who nailed down his eighth save of the season.

Seattle has won three straight and six of its last seven games.

Oakland starter Scott Kazmir (4-1) absorbed his first loss of the season after giving up four runs on eight hits and two walks over six innings.

Brandon Moss slugged a two-run homer for the A's, who have lost three of their last four games.
