In large bowl, combine ketchup, honey, soy sauce, gingerroot and garlic. Add chicken and turn to coat well; marinate for 30 minutes at room temperature or up to 3 hours in refrigerator.

Drain chicken pieces, reserving marinade. Grill chicken on greased grill 4 inches from heat, brushing with marinade during last 10 minutes of cooking, for about 40 minutes or until chicken is tender and no longer pink inside.
