Jairzinho Rozenstruik scores come from behind knockout against Alistair Overeem in UFC on ESPN 7 main event

For the second time, the UFC Octagon was in the nation's capital on Saturday with Washington D.C. playing host to UFC on ESPN 7 at Capital One Arena. Heavyweights Alstair Overeem and Jairzinho Rozenstruik headlined the 12-bout fight card in a night filled with finishes.

Overeem and Rozenstruik are strikers by trade with extensive kickboxing backgrounds.  On paper, the matchup leaned heavily toward the fight being a standup battle but that's not what happened.  Overeem entered the bout on a two-fight win streak and nearly put together the perfect game plan against the undefeated Rozenstruik.

Overeem kept his hands high as he inched forward.  His left hand landed early and often, but "The Demolition Man" wanted to get the fight to the ground.  He secured a takedown in the opening round and controlled Rozenstruik while delivering short punches and elbows.

In the second round, Overeem utilized the clinch to nullify Rozenstruik's offense.  On the outside, he continued to land his left hand.  Overeem kept the strategy up in the third round.  He secured a takedown in the later portion of the frame and delivered some heavy shots.

Rozenstruik picked up the pace in the fourth round.  He unleashed flurries and had Overeem covering up against the fence.  Overeem's defense held up but Rozenstruik inflicted damage.

The pace slowed in the final round with both fighters visibly fatigued.  Overeem was unable to secure takedowns and and his output diminished.  Rozenstruik was behind on the scorecards with the judges having Overeem winning the first four rounds.  In dramatic fashion, Rozenstruik landed a combination that sat Overeem down.  After landing the devastating right hand, Rozenstruik walked away with his hands up, but the fight hadn't been stopped yet.  Overeem immediately got to his feet but stumbled badly along the cage and the referee stepped in with just four seconds remaining.

"It was a really hard fight," said Rozenstruik following the knockout win.  "I don't need too much.  One shot.  One kill."

"Going deep is what we do everyday in the gym and that's what I showed.  I showed some heart out here and knocked him out in the last round.  When you work hard you can do those things," he added.
