Step 1) Combine oil, orange juice, cherry preserves, red wine vinegar and seasoning in a 1-gallon resealable plastic bag; add pork. Refrigerate to marinate for at least 30 minutes.
Step 2) Combine glaze ingredients in a small bowl.
Step 3) Remove pork from marinade; discard marinade. Grill pork over direct medium heat for 15 to 20 minutes, until internal temperature is at least 150°F. Brush with a few tablespoons of glaze the last 2 to 3 minutes of grilling. Remove pork to platter and allow to rest at least 10 minutes. Cut into slices and serve with remaining Cherry Glaze.
