LAS VEGAS – Kevin Gonzalez extended his lengthy winning streak and remained in 122-pound title contention Saturday.

The Mexican southpaw applied pressure throughout his 10-round fight against Colombian veteran Jose Sanmartin, consistently landed the harder punches and won their junior featherweight bout by unanimous decision on the David Benavidez-Caleb Plant undercard at MGM Grand Garden Arena. All three judges – Max De Luca (98-92), Lisa Giampa (99-91) and David Sutherland (97-93) – gave Gonzalez credit for a convincing victory.

Gonzalez (26-0-1, 13 KOs) has won 13 fights in a row since his six-round majority draw with Adalberto Garcia (then 6-6-4) in September 2018. The 25-year-old Gonzalez is the WBA’s third-ranked contender for its super bantamweight champion, Murodjon Akhmadaliev (11-0, 8 KOs).

Sanmartin slipped to 34-7-1 (21 KOs) and lost for the second time in his past three fights.

Sanmartin seemed content to go the distance and didn’t press for the knockout he so clearly needed in the ninth and 10th rounds. Gonzalez out-worked him again in those final six minutes of action and cruised to a lopsided win.

Gonzalez landed back-to-back right hands as Sanmartin came forward with just over 30 seconds on the clock in the eighth round.

Gonzalez unloaded a combination to Sanmartin’s head and body with just under 15 seconds on the clock in the second round.
