  Remove the tri-tip from the fridge and place directly on the grill grates. Insert the probe into the thickest part of the meat. Brush with the garlic-vinegar mop sauce, then close the lid and cook for 15 minutes. Flip the tri-tip and brush with the mop sauce on the other side. Close the lid and continue cooking, flipping and basting every 15 minutes until the internal temperature reaches 130°F, 30-40 minutes total.
