Vanes Martirosyan mostly has competed at or just above the junior middleweight limit of 154 pounds since he turned pro in April 2005.

Like the vast majority of boxers, the 5-feet-11 Martirosyan often has had to struggle to make weight. These past two weeks have been completely different for the longtime 154-pound contender, however, because those six extra pounds have made that typically grueling process much easier for him.

Before his last fight – a 154-pound championship rematch against Erislandy Lara in May 2016 – Martirosyan had to lose eight pounds in the 24 hours prior to their weigh-in.

The 32-year-old Martirosyan feels fresher this week and expects to be stronger than usual when he enters the ring Saturday night for a potentially career-changing chance to upset one of the best boxers in the sport. Gennady Golovkin has fought at the middleweight limit of 160 pounds throughout his 12-year pro career, but Martirosyan (36-3-1, 21 KOs) is about an inch taller than the defending champion and could out-weigh Golovkin (37-0-1, 33 KOs) by a few pounds once their middleweight title bout begins Saturday night at StubHub Center in Carson, California (HBO; 11 p.m. ET).

“I always fought better at higher weight classes,” Martirosyan said during a conference call this week. “Whenever there was a catch weight in my career, I always did better. So I think it’s gonna be good because I don’t have to kill myself to make [154]. I remember when I fought Lara, the day before the weigh-in I was 162. I had to cut eight pounds to make 154. This was 24 hours before the weigh-in. So I kind of had trouble making [154] sometimes.

“But I made it easy, no problem, because, you know, the struggle is like that for all fighters. You know, for a short camp like this, it’s perfect. The weight’s good and everything is good, and we just can’t wait to rock and roll. I’ll be stronger at [160]. I might be bigger. I don’t know. You know what I mean? But we’re good, man. I think 160 is a good weight class for me and we’re gonna be there for a while, I think.”

Martirosyan lost a 12-round unanimous decision to Cuba’s Lara (25-3-2, 14 KOs), who then owned the WBA and IBO super welterweight titles, in their rematch. His first two losses were a 12-round, split-decision defeat to former WBA and WBO 154-pound champ Demetrius Andrade (25-0, 16 KOs) in November 2013 and a unanimous-decision loss to WBC super welterweight champ Jermell Charlo (30-0, 15 KOs) in a 10-round, non-title fight in March 2015.
