MILWAUKEE - Anthony Pettis claimed the UFC lightweight title in his hometown Saturday night, beating champion Benson Henderson by armbar submission in the first round at UFC 146.
Pettis (17-2) ended Henderson's 18-month championship reign in decisive fashion, catching Henderson (18-3) in an armbar while on his back late in the round.
Pettis stretched out Henderson's right arm and abruptly finished the rematch of their memorable WEC bout, beating Henderson for the second time. Henderson verbally tapped out of just his second loss in 20 fights — both to Pettis.
Heavyweight Josh Barnett won his first UFC fight in 11 years, stopping Frank Mir with a big knee to the head midway through the first round at the Bradley Center. Chad Mendes also stopped veteran Clay Guida in a meeting of 145-pound contenders.
