It certainly didn’t come easy, but  Felicia Spencer (6-0) kept her perfect record intact and claimed Invicta’s vacant featherweight title with a fourth-round submission win over a gritty Pam Sorenson (7-3). The bout served as the main event of Invicta FC 32, which streamed live tonight on UFC Fight Pass from FireLake Arena in Shawnee, Okla. Spencer made no attempt to hide her intentions, pressing into the clinch in the early going and pressing until she took the fight to the floor. From there, she moved quickly to the back and made fantastic adjustments to stay in the position despite being very high on her opponent’s body. Once firmly back in place, Spencer started to pound away. With a figure-four around the body, Spencer went hunting for the choke, though Sorenson showed solid defense in lasting until the bell, even if she wasn’t ever able to offer any offense in reply
