Heat grill. Generously pierce lamb chops with fork. Place in shallow dish; add wine. Let stand at room temperature for 15 minutes to marinate.
Meanwhile, in small bowl, combine Worcestershire sauce, rosemary and garlic; mix well. Set aside.
When ready to grill, remove lamb from marinade; discard marinade. Place lamb on gas grill over medium heat or on charcoal grill 4 to 6 inches from medium coals. Spoon half of sauce mixture evenly over chops; sprinkle generously with pepper. Cook 4 to 5 minutes or until browned.
Turn chops. Spoon remaining sauce over lamb; sprinkle with pepper. Cook an additional 4 to 5 minutes or until of desired doneness. Sprinkle lamb with salt.
