Combine all ingredients except steaks in a medium sized bowl.
Place steaks in a Ziploc bag. Pour marinade into the bag. Seal and allow steaks to marinade in the refrigerator for at least 4 hours.
Preheat the grill to high. Brush some oil on the grates.
Drain and discard marinade. Place steaks on the grates and close the lid. Grill steaks for 7 to 9 minutes on each side for medium doneness. Watch closely to avoid flare-ups by opening the lid occasionally. Move steaks to a different part of the grill to avoid charring if flare-ups occur. Flip only once.
Transfer steaks to a platter. Cover loosely with aluminum foil and allow them to rest for 10 minutes.
Season with a little salt and freshly ground pepper before serving.
