single back bunch

i just played some guy who used the ravens and he came out in just a bunch and this reciever was open every time. he motioned the outside reciever towards the sideline then hiked and threw a bullet and he was ALWAYS open. i moved a linebacker over to cover it but then he just hit slants over the middle. any1 know what route that outside reciever could be doing?

verticals thats whats hes doing prolly if u play man he wont be able to do it no more cause zone backs off coverage and thats when he throws it.
