Saturday night was a big night for Jaime Munguia (31-0).  The WBO super welterweight champion destroyed a badly over matched Brandon Cook (20-2) in three rounds in the co-featured bout underneath the Canelo Alvarez-Gennady Golovkin main event that took place in Las Vegas.

The 21-year-old Tijuana, Mexico native defended his title for the first time in July when he won an unanimous decision over Liam Smith.

While the scorecards weren't close in the fight, Munguia received a lot of criticism for the amount of flush punches that were landed on him.

He was very satisfied with the adjustments he made against Cook.

"I felt very good in there and all the work I did in the gym - I think the results reflected that. I believe that I put on a great performance for the fans," Munguia told BoxingScene.com.

At the end of the first round Munguia had Cook pinned against the ropes and hurt him with several punches.  When asked if he knew at that moment if he would stop Cook, Munguia said that he knew he still had to be careful.

"Yes I was thinking that but I was also thinking that he is a very strong opponent and that he has a good chin and he can withstand a lot of punches so I had to take my time," said Munguia who hopes to return to the ring in the fourth quarter.

As for the main event, Alvarez won a majority decision by the scores of 15-113, 115-113, and 114-114. There was a close to 90 minute gap between the end of Munguia's fight and the start of Alvarez-Golovkin so the 21-year-old was able to watch the fight in it's entirety.

Scores on press row were mixed with the majority having scored the fight for Golokvin or a draw. Munguia however agreed with the judges decision to award the fight to Alvarez.

"I thought it was a great fight on a very important date for Mexico. For me it was a great action fight. I also had Canelo winning the fight," Munguia stated.
