Christopher Diaz started separating himself from Jason Sanchez by the third round Tuesday night and never relinquished control of their 10-round featherweight fight in Las Vegas.

Puerto Rico’s Diaz landed an array of counter right hands, left hooks and body shots, and mostly defended himself well on his way to defeating Sanchez by unanimous decision on the Andrew Moloney-Joshua Franco undercard at MGM Grand Conference Center. Judges Tim Cheatham (98-92), Max De Luca (97-93) and Ricardo Ocasio (98-92) each scored their fight for Diaz by big margins.

ESPN televised Diaz’s victory as part of a four-bout broadcast.

The 25-year-old Sanchez (15-2, 8 KOs), of Albuquerque, New Mexico, lost for the second time in his past three fights.
