Irishman Gary ‘Spike’ O’Sullivan takes on David Lemieux on the Gennady Golovkin vs Canelo Alvarez card in Las Vegas on September 15th.

The bout represents a huge opportunity for both guys.

Not just because of the size of the bill their fighting on, but also knowing that an impressive win could set up a world title shot for both of them.

Their styles are similar in that they are big hitting, come forward middleweights, so it should make for a fun fight as long as it lasts.

Speaking ahead of the bout on areas he’s improved on the last couple of years, O’Sullivan said:

“Specifically, I’m more dedicated. I’m a proper athlete these days. I’m very dedicated to my training, which I wasn’t always throughout my career. The past, I suppose two years, I’ve been very dedicated to being a proper athlete.

I think the old Spike, there’s no comparison. I see that in my weight. I make-weight really easy now. I look different. My body shape is different to before and you know, it’s easier when I come to training camp now. I’m just working on my technique and boxing skills, rather than what David does, losing weight in camp. I used to do that one time, as well, myself, and it’s not so good. It’s more like Weight Watchers than training camp for a fight. That’s the difference in me right now.”

The event will be live on HBO pay per view.
