Gennady Golovkin isn’t underestimating Steve Rolls after Andy Ruiz’s upset victory over Anthony Joshua.

Gennady Golovkin (38-1-1, 34KOs) looks to get back into title contention against Steve Rolls (19-0, 10KOs) on Saturday. The bout will be Golovkin’s sixth appearance at the Madison Square Garden in New York, a venue that has become a second home to the Kazakhstan native.

As “Triple G” witnessed Andy Ruiz chop down Anthony Joshua in a stunning TKO victory at the MSG this past Saturday, he was reminded that anything can happen in boxing.

“He (Joshua) feel like a superstar,” said Golovkin. “New opponent, look at Andy Ruiz. Maybe not serious. I know Andy, respect him. Congrats. This boy was coming to fight. Not like a loser, like a fighter.”

Like Ruiz, Rolls enters as the big underdog against Golovkin. He also comes to the fight with nothing to lose, but everything to gain. As Ruiz showed, this can sometimes create a dangerous, hungry opponent.

With the bout being labeled as a tune-up fight for Golovkin, Rolls has also vowed to prove to everyone that this will be no tune-up fight.

“This is boxing, I like this,” said Golovkin. “Everybody has a chance, everybody.”
