In a 6 quart slow cooker place the pork on the bottom. Wrap the bacon around the pork layering it evenly on the top.
In a small bowl whisk together the maple syrup, spicy brown mustard, Worcestershire sauce, and garlic. Pour on top of bacon-wrapped pork.
Cover and cook on low heat for 4 hours or until cooked through to a temperature of 145 degrees (for a light pink center) and 160 degrees. Remove the sauce from the slow cooker and heat on medium high heat in a medium sauce pan. Whisk together in a small bowl the cornstarch and water and add to the maple sauce. Let simmer until thickened.
Remove the pork from the slow cooker and place on a baking sheet. Brush the top of the pork with the maple mustard sauce and broil for 2-3 minutes until the top is brown and caramelized. Enjoy!
