More is at stake between Saul “Canelo” Alvarez and Austin “No Doubt” Trout” than two world titles and the right to stay undefeated.

Back in 2011, Trout won a unanimous decision over Rigoberto Alvarez, Canelo’s brother, for the WBA Lightweight title. Ever since, the Mexican has wanted to avenge the knock on his family.

He will have his chance Saturday night at the Alamodome in San Antonio in a scheduled 12-round bout with Trout. The winner will unify the WBC and WBA Lightweight crowns.

Just four short months ago, Trout dropped Miguel Cotto in a unanimous decision to retain the Texas native's lightweight crown and his pristine 26-0 record.

WBC champ El Canelo Alvarez took more time off after registering a fifth-round TKO of American Josesito Lopez in Las Vegas back in September.

At just 22 years old, Alvarez has basically reached the pinnacle of his weight class and is already 41-0. However, Trout represents Alvarez's biggest test thus far. Both fighters possess raw power as evident by Alvarez winning 30 of his fights by KO, and the southpaw Trout totaling 14 knockouts in his 26 professional fights.

The last time Alvarez fought a southpaw he went 12 rounds with Ryan Rhodes before capturing the TKO in 2011.

Betting Odds: Canelo is a -190 Favorite

Over/Under: 9 1/2 rounds

Prediction: Trout has a one-inch reach advantage, but the speed of both fighters should be the biggest factor. Both will look to score points in early rounds and then back off, avoiding any trap in the corners. Alvarez might need some time adjust to Trout's stance, but eventualy he will learn his opponent's timing and win in a decision.
