MIAMI GARDENS, Florida – Rodolfo Gomez Jr. was considered a test for Diego Pacheco on Saturday night because Gomez hadn’t been knocked out in 19 professional fights.

Gomez proved his durability against the heavy-handed Pacheco, but Pacheco basically beat up the game Gomez throughout their eight-round super middleweight match at Hard Rock Stadium. Judges Fernando Barbosa (79-73), Rose Lacend (79-73) and Rocky Young (79-73) each scored seven of the eight rounds for Pacheco, who won a unanimous decision on the Canelo Alvarez-Avni Yildirim undercard.

The 19-year-old Pacheco, a 168-pound prospect from Los Angeles, improved to 11-0 (8 KOs). The 31-year-old Gomez (14-5-1, 10 KOs), of Laredo, Texas, had his three-fight winning streak snapped by Pacheco.

Gomez never stopped throwing punches during the eighth and final round, but he couldn’t prevent Pacheco from coming forward and landing right hands.

A left hook by Pacheco backed up Gomez about 45 seconds into the seventh round. Pacheco’s right uppercut snapped back Gomez’s head with just over 20 seconds remaining in that seventh round.

Pacheco continued to land overhand rights and right uppercuts in the sixth round. He didn’t seem to hurt Gomez in that round the way he affected him in the fifth round, though.

Pacheco’s right hand backed up Gomez with just under 40 seconds to go in the fifth round. Pacheco buzzed Gomez with another right hand later in the fifth, which made Gomez hold him to help make it to the end of the round.

Pacheco caught Gomez with a left hook that knocked him off balance with just under two minutes to go in the fourth round. He also nailed Gomez with an overhand right toward the end of the fourth round.

Gomez landed a right hand on the inside with just under a minute to go in the third round. Pacheco landed a right uppercut and then followed up with a left hook later in the third round.

Gomez complained that Pacheco hit him behind his head late in the third round.

Pacheco caught Gomez with an overhand right as Gomez missed with a right hand of his own in the middle minute of the second round. Pacheco provided pressure throughout the first round, though there weren’t many clean punches landed in that round.
