All of pressure in this week's fight falls solely on the shoulders of WBA featherweight world champion Leo Santa Cruz, according to former unified 122-pound world champion, Irish star Carl Frampton.

Frampton (22-0, 14KOs) makes the move up in weight to challenge Santa Cruz (32-0-1, 18KOs) for his world title on Saturday night, as the headline bout of a Showtime televised tripleheader live from Barclays Center in Brooklyn.

Televised coverage begins at 9 p.m. ET/6 p.m. PT on SHOWTIME following fights on SHOWTIME EXTREME that begin at 7 p.m. ET/PT.

Frampton realizes that a lot of fans and experts have him tagged as the underdog in the contest, but he's not paying any attention to the odds. He's very confident of getting the upset. 

"Leo seems like a nice guy and he's very respectful. I've been respectful to him. He's obviously a very good fighter. This is a world title fight, so I don't think we need any extra words between the two of us. We're both undefeated and we're looking for a war," Frampton said.

"The last time I was an underdog was 2009 during the Irish championships. I was a massive underdog and everyone who knew me won a lot of money that night. Leo is a great fighter. He's world class. Easily the toughest opponent that I've faced so far. But I think I'm Leo's best opponent as well. I think this has all the ingredients to be a top quality fight. I've had a hard training camp and I'm ready to leave everything in the ring.

"I've got a game plan. I'm not going to blink. We're hoping that 'game plan A' will work, but if not, I've got a few tricks up my sleeve. All the pressure is on Santa Cruz. Everyone is expecting him to win. I'm going to come in there and upset him. I'm here to put on a great performance and bring the belt back home.

"I've gotten a good reception since coming to America and I think it will only grow on fight night. People will appreciate my style and I think our styles will gel well in the ring. I'm feeling strong mentally and physically. I feel like my stamina level has increased with the new weight. I'm eating well and enjoying myself."
