Hector Perez is a natural cruiserweight who was 29 pounds lighter than Juan Torres entering their heavyweight fight Tuesday night.

Perez took Torres’ power well, though, and soundly out-boxed the poorly conditioned, 250-pound southpaw to win a six-round unanimous decision at MGM Grand Conference Center in Las Vegas. Judges Eric Cheek (60-54), Patricia Morse-Jarman (60-54) and Ricardo Ocasio (59-55) each scored their unremarkable bout for Perez by wide distances.

The 29-year-old Perez, of Tamarac, Florida, improved to 6-3. The 33-year-old Torres, of Cypress, Texas, slipped to 5-3-1.

Perez’s victory came in the third of four fights ESPN aired as part of the Joshua Greer Jr.-Mike Plania undercard.
