It was a quick night of work for Gervonta Davis, who demolished challenger Hugo Ruiz via first round knockout on Saturday night in Los Angeles. Davis (21-0, 20 KO,) the World Boxing Association super featherweight champion, stunned Ruiz with a hard right hook just before the bell. Ruiz (39-4, 33 KO) was able to beat the count and make it to his feet, but when referee Jack Reiss asked Ruiz if he wanted to continue Ruiz was silent. After asking multiple times, Reiss called a halt to the action with one second left in round one. Earlier in the first Davis broke Ruiz's nose, which appeared to aid his decision not to continue. Following the stoppage blood poured from the nose of Ruiz, who looked like the much smaller man in the ring against the bigger, stronger Davis.

Davis was originally scheduled to fight former tilist Abner Mares in what would have been Davis' biggest fight of his career to date. But Mares suffered a detached retina, the second of his career, in the lead up to the fight, causing Mares to pull out of the bout. Ruiz took the fight on late notice but has spent his career fighting at 122 and 126 pounds. The naturally smaller man was no match for Davis' devastating power.

At 24 years old, Davis is considered one of the most skilled young fighters in the sport. However, his career to this point has been dominated by setbacks outside of the ring. Saturday's fight was just his second in the last ten months. Davis has had public feuds with promoter Floyd Mayweather, and struggled to make weight on multiple occasions. Davis has also battled repeated legal issues.

After the fight Davis expressed a desire to get back in the ring quickly. A quick return to the ring shouldn't be an issue for Davis: Ruiz landed just three punches before being knocked out, so Davis' body should require minimal recovery before starting his next training camp.
