Carlos Cuadras squeaked through David Carmona in a ten-rounder that could easily have gone the other way.
The former world champion struggled at times during the contest as Carmona sensed an opportunity to cause an upset.
Carmona began brightly and edged the middle rounds and may have cost Cuadras a potential rematch with Roman Gonzalez by stifling most attacks.
At the very least, and on the WBN Scorecard, Carmona deserved at least a draw, although scores came back reading 97-93 (twice) and 96-94 in favor of the more well-known of the two Mexican's.
Cuadras is now set to be given the nod to challenge for the WBC belt in his next contest.

Former world middleweight title challenger Andy Lee moved a step closer to a possible fight with the main event winner by scoring an eight round decision over Keandre Leatherwood.
In a bout that failed to spark, Lee took a 80-72, 79-73, 78-74 nod from the officials at ringside to push on to bigger tests on his path to a final world title shot.
