NEWARK - Shane Carwin entered the Octagon at UFC 111 for his interim heavyweight title shot having never gone into the second round in any of his 11 previous fights. In his four previous UFC bouts, he hadn't even gone past the 2:11 mark.
That first-round streak continues. But, hey, at least he set a new benchmark for distance gone in a UFC fight.
Carwin knocked out Mir 3:48 into the first round to win the interim heavyweight title, a belt Carwin earlier in the week called "the semifinals." With the impressive knockout, Carwin (12-0) earns himself a shot at the real heavyweight champion Brock Lesnar, most likely in July.
"It's a lifetime of work right here," Carwin said.
Carwin got Mir up against the cage for a second time and landed big shots until Mir dropped to the canvas.
"I saw him start to fade and right there, I just let him go," Carwin said.
Carwin landed a flurry of shots to the grounded Mir (13-5), who managed to escape for a moment, until Carwin got his back and kept firing away.
"That was a good fight, but he's still wearing a belt that's a make-believe belt," Lesnar said inside the Octagon.
Earlier in the round, about 43 seconds or so, Carwin got MIr up against the cage and alternated with right hands to Mir's head and right knees to Mir's braced left knee for more than a minute until referee Dan Miragliotta separated the fighters.
Where Mir goes from here is anyone's guess. Maybe Cain Velasquez or Junior Dos Santos.
