Henry Blanco hopped on a cross country flight from Miami first thing Friday morning for his fresh start out West with the Seattle Mariners -- still a big leaguer as he approaches his 42nd birthday in August. And what a memorable Mariners debut he delivered -- with the bat, behind the plate catching ace Felix Hernandez, and even in a spontaneous mound visit. Blanco hit a sixth-inning grand slam to break a scoreless tie and give Venezuelan countryman and good friend King Felix all the offense he needed, and Seattle beat the Oakland Athletics for the second straight game with a 4-0 victory Saturday.
