What happened: Quillan Salkilld submitted Mateusz Gamrot by rear-naked choke in the opening round at UFC Vegas 120. He took Gamrot's back in a scramble and finished the bout with just over 30 seconds left in the round.
Why it matters: The victory over the No. 8-ranked lightweight strengthens Salkilld's case for a higher-ranked matchup. He called for a top-five opponent after the win.
By the numbers: Salkilld has won four consecutive fights in the first round, following three knockouts with the submission of Gamrot.
What to watch: The next lightweight rankings update could clarify Salkilld's position. His next booking will show how quickly UFC moves him toward the division's top five.
