Preheat your oven to 450ºF and move your oven rack to the lowest level.
Sprinkle the roast with salt and pepper. In a small bowl combine the garlic, oregano and butter to form a paste. Brush on the roast and place the roast fat side up in a roasting pan. Place in the oven and bake 20 minutes.
Reduce the oven temperature to 250ºF and bake until the center of the roast reaches 110ºF with a instant-read thermometer, about 1 1/2 hours.
Remove the roast from the oven and cover with foil. Let sit 20 minutes. Serve.
