Canelo isn't first to defend family name

On Saturday, Canelo Alvarez will be fighting for more than a couple of leather belts. He'll be fighting for family pride, and he hopes to reel in a big fish -- specifically, a Trout.

Two years ago, Austin Trout won his junior middleweight title with a one-sided unanimous decision victory over Rigoberto Alvarez, who just happens to be the older brother of Canelo.

This won't be the first time a professional fighter will have sought to avenge a sibling's defeat.

The Baers vs. Joe Louis

Rising heavyweight star Joe Louis faced Max Baer in 1935 in the Livermore Larruper's first fight since dropping the heavyweight title to Jim Braddock. Louis dispatched Baer with a fourth-round knockout. Six years later, Louis, now the champion, was challenged by Maxie's younger brother Buddy. In a wild, action-packed encounter, Baer knocked Louis through the ropes in the first round. The Brown Bomber was unfazed as he knocked down Baer three times in the sixth round. The last time came after the bell, and when Baer's manager refused to leave the ring while arguing the knockdown, Baer was disqualified. Baer received a rematch in 1942 only to be knocked out in the first round.

The Spinks brothers vs. Larry Holmes

In June 1981, heavyweight champion Larry Holmes defeated former champ Leon Spinks in a devastating third-round knockout. In 1985, Holmes was 48-0 and on the verge of tying Rocky Marciano's perfect record. Standing in his way was light heavyweight kingpin Michael Spinks. Leon's little brother stood up to Holmes and took the title with a 15-round unanimous decision. According to CompuBox, Spinks outworked the older Holmes, throwing 130 more punches (697 to 567). He also outlanded Holmes 318-248. To add insult to injury, Michael Spinks beat Holmes again the following year.

The Klitschkos vs. Corrie Sanders

In March 2003, South African Corrie Sanders shocked the world with his stunning second-round stoppage of Wladimir Klitschko, temporarily derailing the Ukrainian's rise to heavyweight dominance. Witnessing the upset was Wladimir's big brother Vitali. The elder Klitschko would get his chance at revenge the following year. In front of 17,000-plus at Los Angeles' Staples Center, Klitschko exacted his family's revenge, stopping Sanders in the eighth round. Klitschko was dominant, outlanding Sanders 230-51 in total punches, according to CompuBox. Before that, in 2000, little brother avenged Vitali's loss to Chris Byrd.
