Using rydurham Sentinel on specific route in Larvel 5.1

I am using sentinel by Ryan Durham http://ift.tt/MSeZd7 with Laravel 5.1.

I used to use Confide http://ift.tt/XgMzel with Larvel 4.2.

With Confide I was able to add an auth to any route like this

// Applies auth filter to the routes within orders/ 
Route::when('orders/*', 'auth');

I've searched through Sentinel documentation for this feature but I cannot find out how to get this done. I can put an auth for say admin or user in the construct of a controller, but I need to have specific auth abilities on specific routes.

My question is, how can I redirect a user who goes to a route only for admin using rydurham sentinel in a clean fashion the same as Confide?
