In a large skillet, bring water to a boil; add asparagus. Cover and cook for 4-6 min. or until almost tender; drain and pat dry. Cool slightly. Thread several asparagus spears onto two parallel, soaked wooden skewers. Grill, uncovered, over medium heat for 2 min. Turn once. Baste with barbecue sauce. Grill for 2 min. longer, turning and basting once again.
