PREHEAT greased barbecue to high heat. Sear chops 1-1/2 min. on each side.
REDUCE heat to medium. Brush chops with barbecue sauce; cover with lid. Grill 4 min.; turn and brush with additional barbecue sauce. Continue grilling 3 to 4 min. or until juices run clear and internal temperature reaches 150°F.
REMOVE chops from grill; place on clean platter. Let stand 5 min. so juices redistribute and chops internal temperature reaches 160°F.
