Mark Lowe could close some games for the Mariners this week, a job he was hoping to secure during spring training. Brandon Morrow has been removed from the closer's role, David Aardsma can't pitch everyday, and Lowe has looked good this season. "They're throwing me a lot, and that's a great thing. It keeps you crisp and ready to go," Lowe said Saturday. "To have the arm strength I've got right now and feel like I did in '06, with the same confidence."
