Henry Blanco hit a sixth-inning grand slam in his Seattle debut to break a scoreless tie, Felix Hernandez pitched seven strong innings to win his third straight decision, and the Seattle Mariners beat the Oakland Athletics 4-0 on Saturday. The 41-year-old Blanco, a .184 hitter with no home runs coming into the game, was an unlikely candidate to deliver the decisive hit for Seattle.
The Mariners signed him Friday, three days after his release by Toronto. He became the oldest Mariners player with a slam.
Hernandez (8-4) struck out five of Oakland's initial eight batters and seven through four innings on the way to eight Ks.
Michael Morse had two doubles among his three hits, including one in the sixth before Blanco's drive stayed just inside the left-field foul pole.
