WINNIPEG – Canadian slugger Sean Pierson snuffed out Kenny Robertson’s wrestling attack for 10 minutes and then survived a third-round comeback bid to secure a majority-decision win. The welterweight bout was part of today’s UFC 161 event at MTS Centre in Winnipeg. It aired on FX after additional prelims on Facebook and ahead of a pay-per-view main card. Robertson lunged forward for takedowns from the opening bell, but Pierson snuffed out the early shots and looked to counter with punches. Robertson’s continued efforts were briefly rewarded with a takedown, but Pierson quickly escaped back to his feet and continued to defend well with each subsequent shot. While Pierson suffered a small cut under his right eye during the striking exchanges, he ended the opening round with a few heavy combinations. Pierson opened up on the feet in the second frame, and Robertson’s aggressive takedown attack all but disappeared.
