The one week wait only built up anticipation for Jared Anderson to continue his knockout streak.

For the fourth time in five fights, the unbeaten heavyweight from Toledo, Ohio failed to allow an opponent to see the second round, making quick work of Hector Perez. Anderson overwhelmed the Florida-bred DominiRican, scoring a 1st round knockout Thursday evening at MGM Grand Conference Center in Las Vegas.

A right hand and left hook left Perez defenseless, with Anderson going in for the kill. Perez was willed to the canvas, where he remained as referee Russell Mora waved off the contest at 1:45 of round one.

“It was definitely too quick, I really wanted to go some rounds tonight,” Anderson told BoxingScene.com. “I was looking for a step up and trained for a step up. We don’t take nobody lightly.”

Both boxers returned to The Bubble for their second fight each, one that was supposed to take place one week ago. The fight was pulled from the July 9 card when Perez’s post-fight urinalysis from his June 18 showed high levels of testosterone, though a subsequent test showed it was natural.

It mattered little by fight night, as the one week delay merely prolonged the inevitable.

Anderson improves to 5-0 (5KOs), closing the show quickly after being extended all the way into the 3rd round by Johnnie Langston on a June 9 card in Las Vegas.

Perez falls to 7-3 (3KOs) in what will likely be his last fight at heavyweight. The 29-year old previously informed BoxingScene.com of his intention to return to cruiserweight.

Eduardo Sanchez and Kenny Davis Jr. made the most of their TV time.

A dramatic 3rd round knockdown by Davis provided the margin of victory, claiming a four-round majority decision in an entertaining lightweight prelim.

Judge Natalie Tyrell had the bout even at 37-37, overruled by matching scorecards of 38-36 turned in by judges Max DeLuca and Lisa Giampa.

Sanchez set a frenetic pace from the opening bell, while Davis punched for efficiency. Solid two-way action came of the opening round, before Sanchez unloaded in round two. The 28-year old from Corcoran, Mexico by way of Guerrero, Mexico launched a fight-best 133 punches in the frame, landing 43 for a 33% connect rate—the same as Davis, who was on the hunt for that one perfect shot.

He found it in round three.

A precision-like left hook to the liver forced Sanchez to drop to a knee for the bout’s lone knockdown. The sequence wasn’t immediately detected by referee Robert Hoyle, leaving Davis to honor the final pre-fight instruction—“Protect yourself at all times”—as he landed a right hand while Sanchez was on the deck before the third man finally ruled a knockdown.

Davis was warned for the infraction prior to the start of round four, one where Hoyle offered a makeup call. Davis’ mouthpiece was in the process of being dislodged as a right hand by Sanchez caught him across the chin to eject it onto the canvas. Time was called as the Reno-bred lightweight was deducted one point.

The questionable call didn’t fully impact the outcome, as Davis had banked enough rounds in order to prevail. He now improves to 3-2 -1(0KOs), while Sanchez falls to 2-3 (0KOs).

Martino Jules made it a perfect 10 in the win column, though had to work every step of the way to preserve his unblemished record.

The unbeaten featherweight prospect from Allentown, Pennsylvania overcame a bloody nose and a stiff challenge from Tajikistan’s Aleem Jumakhonov to claim an eight round majority decision. Judge Adalaide Byrd scored the contest 76-76, overruled by identical scores of 78-74 by judges Julie Lederman and Max DeLuca.

Jules jumped out to a strong start, outworking a tough-as-nails Jumakhonov who never stopped coming forward. A momentum shift came in round three when Jumakhonov (8-3-2, 4KOs) drew blood from Jules, though also fighting through a shiner around his eye.

Surviving a mid-round scare, Jules (10-0, 2KOs) stepped on the gas in round six and never looked back in ultimately putting the fight out of reach.

The three bouts served in supporting capacity to a lightweight headliner between Puerto Rico’s Felix Verdejo (26-1, 16KOs) and Albany’s Will Madera (15-0-3, 8KOs).
