Montserrat Ruiz waited 18 months to return from injury, but a win like the one she had Thursday night proved to be well worth the wait. The Kings MMA competitor from Los Angeles by way of Mexico headlined an Invicta show for the first time and made it count, with an impressive first-round finish of former strawweight title challenger  Janaisa Morandin in the main event of Invicta FC 41 at the Police Athletic League in Kansas City, Kansas. “I don’t care what they say, I’m back,” Ruiz said through an interpreter. Both competitors came out gunslinging. Morandin (10-4) scored with knees in the clinch, but that only seemed to rile Ruiz (9-1) up. She moved forward and backed Morandin to the fence with a flurry of hard-charging power shots, then grabbed a headlock and bulldogged Morandin to the mat.
