UFC bantamweight John Lineker is primed to crack the 135-pound top five after finishing fifth-ranked Michael McDonald with a flurry of punches Wednesday night in the main event of UFC Fight Night from Sioux Falls, South Dakota.

Lineker entered the bout on a four-fight win streak and left with his fifth UFC knockout and first career Performance of the Night bonus against McDonald, who insisted on standing in the pocket and trading with the heavy-handed Brazilian.

Lineker rocked McDonald several times over the first two minutes, before dropping him for the final time with a vicious left hook and following up with some good ol' ground-and-pound.

Certain angles of that fight looked like Goliath Vs a 3 footer. Little guy must have some power that division can't handle. 😳 #UFCSiouxFalls

I like watching that little guy twisting hooks & knockin chins. He will get embarrassed by @DominickCruz or @Cody_Nolove tho. #UFCSiouxFalls
