Turns out there might be something to this welterweight move for Michel Prazeres (26-2 MMA, 10-2 UFC) – even if he doesn’t necessarily want to stay there. The Brazilian powerhouse and former lightweight moved to 2-0 in the division after steamrolling Bartosz Fabinski (14-3 MMA, 3-1 UFC).

The 170-pound contest closed out the FS1-broadcast prelims of Saturday’s UFC Fight Night 140 event at Parque Roca Arena in Buenos Aires, Argentina.

Fabinski rushed forward at the start, but it was Prazeres who slipped the charge and landed a big right hand that sent his opponent crashing to the floor. Fabinski somehow recovered, but Prazeres continued pounding away with punches and elbows as he stepped into mount. Fabinski scrambled free, but Prazeres latched on to a guillotine choke, rolled to the top and squeezed until he got the tap.

Despite the back-to-back wins at 170 pounds, Prazeres – who missed weight in three of his final four bouts at lightweight – asked post-fight for an opportunity to move back down.
