Carl Frampton is a two-weight boxing world champion, first winning the IBF super bantamweight title in 2014, then moving up in weight nearly two years later to win the WBA featherweight title.
ESPN looks at Frampton's top five title fights in his career.
Frampton's finest moment was his victory over Leo Santa Cruz for the WBA world featherweight title at the Barclays Center in Brooklyn.
Frampton -- nicknamed The Jackal -- became Northern Ireland's first two-division world titleholder after he landed the better and more accurate punches to earn a majority decision (117-111, 116-112, and 114-114) over Santa Cruz and take his world title.
Frampton staggered Santa Cruz in the second round, continued to pick him off with fast flurries of punches, and withstood moments of the fight when it turned into a slugfest.
"It was a tough fight," Frampton said after one of the best bouts of 2016.
"I wanted it to be a tough fight because I wanted a fight the people could remember."
