While Charles Oliveira (24-8 MMA, 12-8 UFC) didn’t have much time on the ground against Christos Giagos (15-7 MMA, 1-3 UFC), he didn’t need it, earning a UFC record 11th submission win.

The lightweight bout served as the featured contest on the FS2-broadcast prelims of tonight’s UFC Fight Night 137 event from Ibirapuera Gymnasium in Sao Paulo. The fights followed additional prelims on UFC Fight Pass and aired prior to the main card on FS1.

The two men exchanged punches in the early going, with Giagos looking to remain a moving target and not get himself trapped against the fence. Oliveira was largely patient from the center, waiting on Giagos to give him an opening for the takedown. Giagos kept himself tight in his striking combinations, not allowing much room to approach. Oliveira did time a takedown perfectly late in the frame, but Giagos worked himself back to his feet with relative ease. A second takedown attempted was defended well just before the bell.

Oliveira was more aggressive with his striking in the second, though Giagos countered well in the exchanges. Still, Oliveira was controlling the position from the center and forcing Giagos to fight with his back against the cage. Just past the halfway mark of the frame, Oliveira sensed his opportunity to move inside, immediately taking the fight to the floor and finding his opponent’s back. From there, he moved the arm quickly under the neck and squeezed, earning a quick tap from Giagos and moving past UFC legend Royce Gracie for the most submission wins in UFC history with 11 career victories via tapout.
