Bruce Carrington slowly took over the fight and ultimately closed the show in style.
A right hand rocked Carlos Castro, sparking a five-punch combination to put Castro flat on his back. The visiting boxer attempted to beat the count but the fight was waved off, prompting a celebration by "Shu Shu" who is now the full WBC 126lbs title, at 1 minute, 29 seconds into the 9th round.
The performance marked the first stoppage on Saturday's show after three straight distance fights earlier in the evening.
