In a large resealable plastic bag, combine the first nine ingredients; add the pork. Seal bag and turn to coat; refrigerate for 8 hours or overnight.
Drain and discard marinade. Using long-handled tongs, moisten a paper towel with cooking oil and lightly coat the grill rack. Grill pork, covered, over medium heat about 4 - 6 minutes per side, or until just cooked through. Let rest for 5 minutes before serving.
