Daquan Arnett gives Miguel Zuniga a boxing lesson on June 1 in Sunrise, Florida.

Shinsuke Yamanaka retained his WBC bantamweight title Saturday night in Japan by putting Tomas Rojas to sleep with a vicious left hook in the seventh. Check it out:

Yesterday at the Echo Arena in Liverpool, David Price put Audley Harrison--both the fighter and his career--to sleep with a series of sickening straight rights.

And as a bonus, here's British heavyweight rival Tyson Fury's eloquent response to the KO:

Canadian middleweight prospect David Lemieux had lost a lot of his shine coming off losses to Marco Antonio Rubio and former 154-lb. titlist Joachim Alcine, but he still has nitroglycerine in both hands, as demonstrated by his chilling knockout last night of a hapless Alvaro Gaona. Check out the straight right that plants Gaona on his posterior near the end of the first round, and then the vicious left hook that puts Gaona to sleep shortly thereafter.

A few seconds after getting staggered, Escalante comes back with a ridiculous right hand that puts Miranda to sleep. Check out the 5:34 mark in the video:

I've been a bit down about all the recent cancellations (Rios-Gamboa, Peterson-Khan 2, Ortiz-Berto 2 -- the last 2 due to positive PED tests), but these two massive knockouts over the weekend deserve recognition:

Mikkel Kessler TKO 4 Allan Green - Instant wave-off

Karim Mayfield TKO 5 Raymond Serrano - The fight-ending blow occurs at the end of the fourth round, at the 2:49 mark in the video
