Jairzinho Rozenstruik picked up the biggest win of his career Saturday night, but it didn't come without adversity.

The UFC heavyweight contender knocked out Alistair Overeem with just five seconds to go in the UFC D.C. main event at Capital One Arena in Washington, D.C.

A left punch followed by a massive right is what finished "The Demolition Man."

Overeem was ahead on all three judges' scorecards heading into the fifth round and before Rozenstruik's finishing sequence. The 39-year-old picked apart the less-experienced Rozenstruik with his veteran savvy, especially during the first three rounds.

Up until the finish, Rozenstruik struggled to put together much offense throughout the nearly 25-minute contest. But he started having more success toward the end of the fight when Overeem appeared tired.

The win marked Rozenstruik's fourth in the UFC, all of which have taken place this year. Rozenstruik is one of the rising stars in the heavyweight division, and his victory over Overeem should move him into the top-10 rankings. Overeem was ranked No. 6 heading into the bout.

Overeem, a former UFC title challenger, was riding a two-fight winning streak before Saturday's loss.
